The Ph.D. course iRALL School 2016 opens on October 16. Now one week has past, during which time, many renowned professors gave extraordinary theoretical lectures, covering geotechnical engineering, engineering geology, disaster prevention and mitigation etc.

 

On October 17, Professor NiekRengers, who used to be the president of International Association for Engineering Geology (IAEG), gave lectures on the composition of academic thesis. He elaborated on the structure and gist in every part of thesis. Finally, he humorously concluded with “KISS” principle—“Keep It Short and Simple”, which stressed the conciseness of thesis.

 

Research Hu Wei, from Chengdu University of Technology, lectured on the physical modelling experiment of landslides, ring shear experiments and liquefaction. Taking Kualiangzi Landslide in Fengdian as an example, he explored the sliding mechanism of translational landslide, and liquefaction phenomenon in the experiment. During the lecture, Mr. Hu constantly exchanged comments and ideas with students.

 

Professor Niek Rengers continued the topic in the afternoon and patiently answered all the questions proposed by the Ph.D. candidates. At last, he assigned homework to students for their improvement of writing by practice. Afterwards, Researcher Hu Wei analyzed the physical modelling of landslides in detail, and introduced the operation principle of centrifuge in our laboratory. All the Ph.D. candidates had great interest in the physical modelling application of centrifuge. After the lecture, Researcher Hu Wei led all the Ph.D. candidates to visit the centrifuge laboratory in our university.

 

Professor Huang Yu, who is the secretary of the party committee in College of Civil Engineering of Tongji University, lectured the numerical simulation of collapse, landslide and large scale of debris flowand compared the numerical simulation methods of different types, in which he emphasized the SPH model, based on which he analyzed different geohazards, and expounded the importance that numerical simulation plays on hydrodynamics.

 

On October 18, Professor Mauri McSaveney from GNS Science, New Zealand, gave a lecture on the formation and evolution of fault crushed belt and stated typical fault cases.

 

Professor Yu Bin from Chengdu University of Technology has deep understanding on debris flow. He made many achievements with experience of participation in national disaster prevention and mitigation projects. He lectured about the investigation methods and prediction of debris flow, which gave a glimpse to students about the debris flow investigation methods.

 

Professor Fan Xuanmei, from Chengdu University of Technology, is dedicated to the research of geohazard induced by earthquake, remote sensing, geological information system applied in geological disciplines, geohazard assessment and control etc.  She is the winner of the first prize of National Scientific and Technological Progress Award,and now is the secretary of iRALL School. During her lecture, she expounded on the disaster chains of Wenchuan Earthquake and gave examples to make it simple for students to understand the influence that earthquake had on geohazards development and distribution.

 

Dong Xiujun and Huang Jian from Chengdu University of Technology are outstanding young researchers in the school. They led students to visit unmanned aerial vehicle(UAV) and expounded large scale landslide monitoring and early warning system.

 

On October 19, Researcher Lan Hengxing from Institute of Geographic Sciences and Natural Resources, CAS lectured the strength characteristics, deformation and failure mechanism, failure mode of rock and rock mass, the analysis method of rock mechanics, and different elements affecting rock strength.From easy to difficult, the lecture was lucid and vivid. Researcher focused on the classification standard of rock and made large amount of experiments, and quantitively analyzed the rock stability by model. 

 

Mr. Dong Xiujun from Chengdu University of Technology expounded the application of 3-D space image technology in geological engineering. 3-D space image technology mainly includes 3-D laser scanning technology and digital photogrammetry technology. 3-D laser scanning technology acquires coordinate data of 3-D space point clouds with laser scanning device as platform. Digital photogrammetry is to acquire digital color photo by digital camera close shot or unmanned aerial vehicle shot at low altitude and to rebuild the coordinate digital information of 3-D space point cloud.

 

Mr. Huang Jian from Chengdu University of Technology elaborated on the key technology of geohazards monitoring and early warning with engineering cases.

 

On October 20th, Dr. Wang Gonghui from Disaster Prevention Research Institute, Kyoto University, is an expert in international landslide liquidation and internal structure of landslide dam induced by earthquake,who is dedicated to the research of mechanism of landslide and debris flow under different circumstances for a long time and makes great achievements which are recognized by international community. He works as invited reviewer for more than 20 international SCI journals like Nature Geoscience.  In his lecture, he mainly introduced the initiation and movement mechanism of large scale landslides, including the movement mechanism of landslides induced by earthquake and rainstorm. He also introduced the sliding experiment of landslide in sink under the rainfall condition.

 

Professor Cees Van Westen, from ITC, the Netherlands, is an expert in remote sensing and geological information in natural disaster and risk assessment application, who opens courses relevant with natural disaster and risk assessment in Italy, France, Argentina, India, Nepal etc. He is also the Chief Information Officer of ITC hazard Management, introducing the types, discovery, recognition, monitoring and early warning, risk assessment and control of large landslide,and the influence caused by landslides hazard and the latest research progress. With large amounts of data and diagrams, Professor Cees Van Westen made it simple and easy for students to understand.

 

Students were very satisfied with the first week of course. During which time, they were encouraged by the strict attitude of teachers and lively atmosphere they created,totally focused on the class, actively taking notes, asking questions, and exchanging ideas with teachers. From iRALL School, not only do students have an opportunity to learn from the renowned experts in this area but also strengthen their expertise.
