摘　　要：华北平原地裂缝近年来呈快速发展趋势,给人民的生产生活造成很大威胁。本文对地裂缝的影响因素进行分析,认为基底构造单元是地裂缝发育的控制因素、全新世地质环境控制非构造地裂缝的分布、基底断裂构造蠕滑控制地裂缝的规模。地形地貌、岩性结构、地表水、地下水、地震、地面不均匀沉降、持续干旱、地下岩溶和人类工程活动等因素影响地裂缝的发展。地裂缝的形成非单一因素造成,而是多种因素复合作用而导致。探讨地裂缝的影响因素对研究华北平原地裂缝形成机理与灾害防治具有重要意义。In recent years,the ground fissures in the North China Plain have been rapidly deteriorating and are threatening local living conditions and production.This study analyzes the major factors influencing the ground fissure.The main controlling factors include the basement structure,the Holocene geological environment and the basement structure creep.Topography,geomorphology,lithology,surface water,ground water,earthquakes,ground surface subsidence,continuous drought,underground karst and human engineering activities are the factors that affect the development of ground fissures.It is considered that a single factor is not solely responsible for the formation of ground fissures in North China but rather a combination of related factors.It is significant to study the formation mechanism and hazard control of ground fissures in the North China Plain.
