【摘要】：随着道路工程等建设活动逐步向城市周边山体发展,在暴雨等气候条件下,因人为工程活动而诱发的滑坡类地质灾害频发,如何预防与治理此类灾害成为城市建设的新课题。本文以贵阳黔灵湖大桥滑坡为例,根据工程地质调查及勘查的成果资料,分析了该滑坡的发育历史,变形特征及形成条件,重点阐述在对该滑坡勘察时以收集地质资料及地表地质调查、工程测量、钻探、工程物探、岩土试验多种手段相结合的勘察方法,尽可能准确的划定滑坡的范围及滑动面等滑坡要素,以及利用现场试验结果及参数的反演计算等方法,使得计算参数更加符合实际情况。并在此基础上对滑坡的稳定性进行了分析,最后提出了滑坡防治的措施。
[Abstract]:With the gradual development of road engineering and other construction activities towards the mountains around the city, landslide geological disasters caused by man-made engineering activities occur frequently under the climatic conditions such as heavy rain. How to prevent and control such disasters has become a new topic in urban construction. Taking the landslide of Qianling Lake Bridge in Guiyang as an example, the development history, deformation characteristics and forming conditions of the landslide are analyzed according to the results of engineering geological investigation and exploration. In this paper, the methods of collecting geological data, surface geological survey, engineering survey, drilling, engineering geophysical exploration, geotechnical test and so on are described in detail. The range and sliding surface of landslide are delineated as accurately as possible, and the method of inversion calculation of field test results and parameters is used to make the calculation parameters more in line with the actual situation. On the basis of this, the stability of landslide is analyzed, and the measures of landslide prevention and control are put forward.
