Research on the Mechanism of Fracture Causes in Wenjia Camp,Xiong'an New Area
摘要
Abstract
Taking the typical ground fracture in Xiong'an New Area--Wenjia Camp Fracture as the research object,the surface deformation characteristics caused by over-exploitation of groundwater in depth through field investigation,drilling and geophysical exploration are analyzed combined with Abaqus numerical simulation.The development and distribution pattern of the Wenjia camp cracks and the profile morphology characteristics are re-vealed,and the mechanism of its genesis and evolution process are discussed.The results of the study show that the Wenjia camp cracks are composed of two crack belts with a general direction of 15°～30°,and the extension lengths of the disaster-causing points of the two cracks are 90m and 200m,respectively,and their damage modes are manifested as cracks in the house walls and pits on the ground surface;the cracks of the Wenjia camp are un-derneath the shallowly buried ancient river channel,and the direction of the cracks is controlled by the course of the ancient river,which is typical of the ancient river channel-control type of the ground cracks.The formation and evolution of the cracks can be divided into three stages as the gestation stage,the formation stage,and the ex-posure and expansion stage.关键词
