摘要
本文根据1987年在化隆盆地所进行的1∶5万区域地质调查所得的资料,综合分析了该区滑坡的分布规律及其特征,新构造的断裂、节理、褶皱等岩石破裂和弯曲变形的应力场特征,滑坡的发生与新构造应力场的关系等。认为在化隆盆地内部进行农业、公路和水利水电建设时,不仅要考虑河流侵蚀、边坡条件和有效临空面等滑坡发生的外在条件,还应特别注意北西—南东和北东—南西两个易发生剪切破裂变形的方向。
Based on the data obtained from regional investigation on geology in scale of 1:50,000, carried in Hualun basin in 1987, the research analyses the distribution rule of landslide and its characters in the region, the stress field characters of rock cracking, meandering and deforming such as the faults, joint and fold of new tectonic, the relationship of landslide with the stress field, etc..At the same time it suggests that when the farming, construction of road and water conservancy or power are conducted, not only the river erosion state, slope conditons and effects and other external conditions for the occurrence of landslide, but also the directions in northwestern to southeastern and northeastern to southwestern, being easy to be sheared and cracked, must be taken in consideration.
