The Geohazards Features and Management of Zhongxian-Wuhan Gas Pipeline in Mountainous Areas
Zhongxian-Wuhan Gas Pipeline (ZWGP), put into operation at the end of 2004, is a part of the West-East Gas Pipeline Project of China. From Zhongxian to Yichang, about 400 kilometres in distance, the pipline goes through the mountainous area where geological conditions are complicated. Zhongxian-Wuhan pipeline is one of the the most outstanding piplines sufferring from geohazards in China. Geohazards investigation, risk evaluation and control engineering have been carried out since the pipline in service. This paper is to sum up the geohazard features and experiences of geohazards prevention and treatment. Based on 3 rounds of geohazards investigation along the pipeline, more than 183 geohazards sites were identified, including 96 landslides, 77 unstable rocks and 10 debris flow gullies. This article summaries the scale and distribution of geohazards along the pipeline, as well as the harm features of the pipeline. It is also introduced in this paper the geohazard management adopted by ZWGP, including the principles of geohazard prevention, running program, and frequently-used prevention methods.
