| Wuzhou City is a typical mountain town in Guangxi autonomous region,a steep mountain slope,more housing is built close to the mountains.Construction activity greatly changed the topography of the original slope conditions, geological conditions and natural stability;At the same time, due to historical reasons, the construction of buildings without planning, drainage layout unreasonable, such as inadequate drainage facilities.These works of human activities on the mountain slope stability caused tremendous impact, in the infiltration of rain and erosion role, easily produced landslide.June 8, 2006 morning, Wuzhou City in just a few hours, rainfall reached 300 mm. By the heavy rainfall, the impact of flash floods, triggered a number of large scale distribution of a wide range, the danger of landslides, collapse, mud-rock flows. According to the survey, this time a total of over 2,000 geological disasters, causing 13 people were killed and 28 people were injured, direct economic losses of about 650 million yuan. For the protection of urban safety and reduce the country and the people and property losses, the autonomous regional government, the Wuzhou municipal government launched the city's comprehensive management of geological disasters. In this paper, a full investigation to collect existing landslides in Wuzhou City of exploration, design and construction information, combined with additional investigation and on-site tests, on the basis of this, the use of mathematical statistics spss software for statistical analysis to identify the relevant laws, and are rock Soil parameters and estimated the average interval, and through statistical analysis presented in Wuzhou City-wide formation and weathering of the strong morals of the standards division. Through the 22 bolt (Cable) bond strength characteristics of the anti-balance analysis, are given control of geological disasters in Wuzhou City in the design characteristics of bond strength bolt value of the recommended values.
