摘要
通过对狩猎场斜坡的形态、地质构造、地层分界等信息进行获取,并进行综合稳定性分析,从而给予治理意见,保障周围居民的安全.主体采用高密度电法进行勘探,选取其中一条物探线加以少量的钻孔验证,从而获取数值模拟所需要的地质剖面图,设置合理的参数代入FLAC3D进行计算.结合物探手段与数值模拟,得出该斜坡在天然工况下处于稳定状态,但局部地区仍然有沿着软弱带滑动的风险.工程实际表明,合理的物探线布设并结合少量的工程钻探可提高勘探数据的精度,FLAC3D软件模拟切坡建房类斜坡的岩土体破坏具有一定的优势,为后续地质灾害的治理提供有力保障.
Abstract
By obtaining information on the shape,geological structure,and stratigraphic boundaries of the hunting ground slope and conduct comprehensive stability analysis,provide governance suggestions and ensure the safety of surrounding residents.The main body adopts high-density electrical method for explora-tion,selects one geophysical exploration line and conducts a small amount of drilling verification to obtain the geological profile required for numerical simulation,and sets reasonable parameters to be substituted in-to FLAC3D for calculation.Combining geophysical methods and numerical simulations,it is concluded that the slope is in a stable state under natural conditions,but there is still a risk of sliding along weak zones in some areas.Engineering practice has shown that reasonable layout of geophysical exploration lines combined with a small amount of engineering drilling can improve the accuracy of exploration data.FLAC3D software has certain advantages in simulating the rock and soil damage of slope cutting and building,which provides strong support for the subsequent management of geological disasters.
