摘要

以刘少奇同志故居管理局园区的滑坡地质勘察及治理工程为例,介绍了高密度电阻率法、直流电测深法和地震地质映象法等的综合应用。工程采用温纳装置、斯龙倍格装置,设计了一组适合该区域地质特征的技术参数,通过对岩溶的发育形态、规模、深度进行探测分析,确定了该区岩溶范围与溶洞的分布状况以及滑移面的变化趋势。结合钻探资料对整个园区的地质灾害程度进行了综合评价,并提出了运用高压旋喷灌浆的治理方案。经验证,该园区的滑坡治理措施取到了较好的效果。
To take the landslide geological investigation and harness engineering in late Comrade Liu Shaoqi's former residence administration garden site as an example,introduced integrated application of high density resistivity method,direct current electric sounding method and seismic -geologic imaging method etc.The project has used Wenner device and Schlumberger device and designed a set of technical parameters adaptable to geological characteristics in the region.Through detection and analysis of karstic development pattern,scope and depth,have determined karst extension,distribution of karst caves and gliding surface movement trend.Combining with drilling data carried out hazard risk comprehensive assessment of whole garden site,and a high pressure jet grouting harness scheme put forward.After verification,confirmed that the landslide harness measures have acquired rather good effects.
