摘　　要：通过现场调研、工程地质调查以及经验分析等手段,研究了将军坟变形破坏特征,分析了将军坟稳定性影响因素。结合FLAC 3D数值模拟方法,分析将军坟在自重应力、粉质黏土局部积水和地震3种情况下位移场和应力场特点和规律,着重揭示了不同等级地震作用下坟体结构变形破坏趋势以及动力学响应特性,并提出针对性的防治措施,包括完善坟体附近排水设施建设,并最低按照Ⅵ级地震设防,同时对坟体北侧抗震能力弱的区域采取加固措施。The deformation and failure characteristics of the Jiangunfen grave,and the factors affecting the stability of tlie tomb are analyzed in this paper by means of field investigation,engineering geological investigation and empirical analysis.The displacement and stress field characteristics have been studied under the three conditions of gravity stress,local water accumulation in silty clay and earthquake based on the numerical simulation method of FLAC3D,which reveals the failure trend and dynamic response characteristics of grave structure different earthquake levels.Then some prevention and control measures were put forward including improving the construction of drainage facilities and reinforcement measures on the nortli side of the grave,where the seismi ccapacity is weak.Meanwhile,the seismic fortification criterion should be in accordance wit!i at least level of VI earthquake.
