贵州盘南电厂响水水库下汤章滑坡体勘察与治理

Investigation & Correction of Xiatangzhang Slide Mass of Xiangshui Reservoir,Guizhou Pannan Power Plant

贵州盘南电厂响水水库下汤章覆盖层滑坡体处于响水水库库首的右岸,基岩为顺向坡,且其上分布较多民宅,为贵州盘南电厂的主要工程地质问题。为此,对该滑坡体进行了详细的勘察,并根据试验参数值、反演分析及工程地质类比法综合分析方法,确定其稳定性计算参数,提出了先遏止滑坡的下滑趋势的处理措施后进行永久性加固的治理方案,随着处理措施的相继实施,已基本控制了该滑坡的下滑活动。

The Xiatangzhang slide mass located on the right bank of the head of Xiangshui reservoir,its foundation rock is consequent slope,there are many houses owned by local people on it,this is main engineering geological problem of Guizhou Pannan Power Plant.After investigating the slide mass in detail,according to test parameters and calculating stable parameters determined by inversion analysis and comprehensive analysis used by engineering geological analogy method,the engineers raised a correction scheme to hold back its slide tendency at first,then to carry out a permanent reinforcement.These treatment measures have been carried out in succession,the slide action of the mass has basically been controlled.
