摘　　要：对于滑坡地质灾害治理,根据地形地貌、地质情况及周边环境情况等因素,采用抗滑桩结合锚索、格构梁结合锚索等措施较为可靠。以广州市花都区茶园经济社大树岭滑坡地质灾害治理工程为例,根据滑坡地质灾害情况,采用下部抗滑桩加锚索,上部放坡加格构梁锚索的支护形式。使用Midas/GTS建模,针对滑坡及治理设计建立有限元数值模型进行分析。边坡治理完成后的监测数据结果显示,其变形在设计控制范围内,验证了治理工程设计的合理性。For the control of landslide geological disasters,it is more reliable to adopt measures such as anti-slip piles combined with anchor cables and lattice beams combined with anchor cables based on factors such as terrain,geology,and surrounding environment.This article takes the geological hazard control project of Dashuling landslide in Chayuan Economic Society,Huadu District,Guangzhou City as an example.Based on the geological hazard situation of the landslide,a support form of lower anti slip piles and anchor cables,upper slope and grid beam anchor cables is adopted.Midas/GTS modeling is used to establish a finite element numerical model for landslide and control design for analysis.The monitoring data after the completion of slope treatment shows that its deformation is within the design control range,which verifies the rationality of the treatment engineering design.
