豫北平原地裂缝发育影响因素初步分析

通过对豫北平原地裂缝调查,共发现地裂缝48处,部分裂缝在发生及发展过程中对房屋、道路、农田造成破坏和威胁。本文分析了豫北平原地裂缝的发育的时空规律,通过地裂缝和地层岩性、降水、地下水、活动构造、地面沉降、地震等各种影响因素进行了分析,认为本地区地裂缝的形成并非单一因素,而是多种因素共同作用发生。

ANALYSIS OF REASONS FOR LONGYAO GROUND FRACTURE

According to the ground fissure investigation of Northern Henan Plain ,it was found to 48 ground fissures in the ground,Part of the ground fissures damage and threats to houses,roads,farmland in the occurrence and development process. This paper analyzes the spatial and temporal development of the law to Northern Henan Plain ground fissures.According to the analysis of various factors such as the ground fissures and strata lithology,precipitation,groundwater,active tectonics,ground subsidence,earthquake and other factors,it is considered that it is not a single factor to the formation of ground fissures in the Northern Henan Plain,but a variety of factors in common.
