Workshop on Zhangmu landslide project was held in Chengdu On March 10, 2013. This meeting was host by Institute of Mountain Hazards and Environment (IMHE), CAS, aiming to discuss the new progress and next step work of Zhangmu project. Experienced researchers Wang Gongxian, Wang Lansheng were invited to the meeting. Mr.Liu Wei, director of the Geologic Environment Division of the Department of Land and Resource of Tibet Autonomous Region，Mr. Duan Xiaonan, director of Division of Ecology and Environmental Sciences of Bureau of Science and Technology for Resource and Environment, CAS also attended the meeting. 

Researcher Wei Fangqiang, vice-director of IMHE presided over the meeting. IMHE Researcher Chen Ningsheng reported the progress and achievement of Zhangmu exploration. Researcher Wang Quancai reported the preliminary proposal to integrated control measure against  Zhangmu landslide. Researcher He Siming introduced the exploration and prevention of collapse in the back mountain of Zhangmu during the meeting.

Experts discussed the research progresses and integrated control measures after the briefing, and they all agreed with that by using of new method, this exploration developed deeper investigation, and acquired a lot of information about the structure, border, history and characteristic of Zhangmu landslide. Especially the application of trace element analysis to the study and integrated underground water level in boreholes help us to find out the distribution and route of underground water. Meantime, experts carried out an in-depth discussion of the cause of ancient rocky slide and the effect of underground water.

After that, experts suggested researchers should develop deeper study on the causes of ancient rocky slide, the impact of earthquake to landslide, and the effect of underground water. Experts also suggested researchers using grade treatment method, considering urban construction and economic development, and be aware of underground water draining in next step work.
