Chengdu Part of iRALL 2018 Successfully Ends

Started on October 15th, iRALL 2018 ended its preceding courses in CDUT. The rest courses will be carried out at the Beichuan field base, combining theory with practice. During the Chengdu session, many international experts gave wonderful lectures, referring to geotechnical engineering, engineering geology, disaster prevention and mitigation, etc..

On October 16th, Prof.Mauri McSaveney, from New Zealand Geological Survey, gave a lecture titled “Fragmentation and some new thoughts of large long runout”, elaborately introduced the collapse landslide and long-distance landslide. After the lecture, the students actively raised some questions and had in-depth discussions with the Professor. Besides, Mauri showed some interesting landslide cases and landscapes encountered in his researches, which attracted students’ interest and attention. In the end, he analyzed the current situation of landslide research.

Then, Prof. Wang Gonghui from Kyoto University of Japan elaborated the happening and motion of large landslides on the topics of “Initiation and motion of large landslides” and “Trip to some recent landslides in Japan”, and shared many new views and relevant data. He also listed some recent landslides happened in Japan, showing us many images and materials, and made in-depth analysis on different types of landslides.

Prof. H. Havenith, from the University of Liège, gave a lecture titled “Contribution of geophysics and modelling to the assessment of multi-hazards caused by earthquake in mountain region”. The professor used his vivid body language to show us the principles and monitoring methods of the geohazards monitoring system. Everyone in the classroom listened with great interest and actively communicated with the teacher.

On the morning of Oct. 16th, Prof. Xu Qiang gave a lecture titled “Monitoring and pre-warning of large landslides”. He elaborately introduced the landslides monitoring technologies, including methods of displacement monitoring and environmental factors monitoring. He also introduced the methods of early warning, and made case studies on typical landslides. Students made active communications with the Professor.

Then, Prof. Xu and Prof. Hu led students of iRALL 2018 to do field investigation at Kualiangzi Research Base, Deyang, Sichuan.

First, Prof. Xu led everyone to observe the shape of the entire landslide in distance, and explained the history of the landslide, the characteristics of the landslide deformation, and mechanism of the landslide. Then, professors led students to observe the foreland of the landslide, inspected various signs of deformation, and explained the details combined with the exhibition board. Later, professors led students to the top of the landslide, and divided the boundary of the landslide. Prof. Xu kept communicating and discussing with the students, exchanged views, and answered questions raised by the students. Prof. Xu's vivid explanation deepened the impression of the students to Kuaziliang landslide. The students have a deeper understanding towards large horizontal-layer landslides.

This field trip provided a great opportunity for students to investigate landslide closely. It not only combined theories with practice, but also improved students’ field investigation ability. Through this trip, a strong relationship between teachers and students was built up, too!

In the next ten days, these teachers and students will go to Beichuan research base for further study and field investigation. They will gain more knowledge and more experience there.
