摘　　要：建设场地或场地附近有地裂缝穿过时,工程设计和施工前应进行专门的场地地裂缝勘察。建设在地裂缝场地的建筑物应根据建筑物的重要性类别、结构形式和地裂缝的活动性质合理确定避让距离,以确保建筑物的安全。文章以西安f8地裂缝局部详勘为例,根据次生地裂缝分布在主地裂缝南侧的规律及初勘时所确认的南侧地裂缝坐标,推断场地北侧应该不存在次生地裂缝,据此制订了以南为主、排查北侧的勘察方案。经过现场勘察,确认了场地南侧为主地裂缝、北侧不存在次生地裂缝的推断,缩短了勘察时间并节约了勘察费用,对同类场地的地裂缝勘察有一定的参考作用。When there is fracture crossing the construction site or near the construction site, special ground fracture investigation should be carried out before engineering design and construction. For the buildings in the ground fracture, it is necessary to rationally determine the required secure distance according to the building＇s importance categories, structure form and the nature of the activities of ground fracture, in order to ensure the safety of the building. Taking Xi＇an f8 ground fracture local detailed investigation as an example, based on the rules of the secondary fracture in the south side of the main fracture, and the preliminary investigation confirmed the south side of the fracture coordinates, inference on north side of the site does not exist secondary fracture. Therefore, an investigation program was formulated about mainly to the south, eliminate the north side. Through site investigation, it is confirmed that the ground fracture in the south is the main and there is no secondary fracture on the north,thus shortening the investigation time and saving cost. It is of certain referential value for the similar ground fracture investigation.
