摘要:
滑面(带)的识别是滑坡调查中的关键性问题之一,它对于滑坡稳定性研究及工程整治设计具有重要意义。本文将滑坡滑面(带)的基本类型分为岩质滑面、堆积层滑面及土质滑面,并从滑面的地质特征如镜摩擦面、擦痕、泥化带、定向排列的菱形剪力体等方面入手,归纳出滑坡滑面的主要识别方法,包括简易力学分析、野外地质判断、现场勘探、位移监测和地球物理探测等,并分别阐述了它们的适用性。
Abstract:
Identification of landslidingsurface is the crucial problem of landslide investigation and research. It is also important for landslide stability and construction design. The basic type of landslidingsurface is categorized to rock surface,sediment surface,and soil surface. The geological characters of landslidingsurface can be classified as smooth friction surface,striation,mudding zone and diamond shearing wedge with directional range. Based on this classification,it is generated that the main methods for landslidingsurface identification contains mechanical analysis,field geology judgment,site exploration,displacement monitoring and geophysical detection. Applicability of these methods is also discussed in the paper.
