基于河道葫芦洞采空区地质影响勘察与模型分析

Investigation and Model Analysis of Geological Impact Based on River Calabash Hole Mined-out Region

水利工程基础虚空问题,是导致地质不均匀沉陷的重要因素,不仅使水工建筑物发生显著内应力改变,而且严重威胁着水工结构的安全。文章针对长沟泵站工程闸址区采砂葫芦洞问题,对河道葫芦洞采空区进行了地质勘察和模型分析,探究了河道葫芦洞采空区地质影响,供类似河道工程建设时参考。

Void foundation problem of water conservancy project is an important factor leading to the uneven subsidence of geology.It not only changes the internal stress of hydraulic construction significantly,but also threatens the safety of hydraulic structure seriously.River calabash hole mined-out region undergoes geological investigation and model analysis in the paper aiming at sand excavation calabash hole in Changgou Pumping Station Project sluice site,and the geological impact of river calabash hole mined-out region is explored,thereby providing reference for similar river projects during construction.
