摘要

在调查、分析唐山市古楼庄地裂缝的时空分布特征、活动性及其危害的基础上,系统分析了地裂缝形成、发展的内、外动力因素。得出地表地裂缝生成的主要原因是其地下深处可能存在隐伏活动断裂的活动(蠕动),该活动断裂为1976年唐山大地震发震构造—唐山断裂带东支唐山矿F5断层之延伸,而小煤矿采空塌陷加剧了地裂缝的发展,是诱因。从力学原理入手,对地裂缝生成的机制进行了分析,并对地裂缝可能的发展趋势进行了预测。
based on the investigation of the spatial-temporal distribution,mobility and hazard of the Gulouzhuang ground fissurs in Tangshan city,systemic analysis has been done on external agents and internal agents for its formation and development.As the conclusion shown,creep of the buried fault is the main cause for the existing surface geo-fracture.This active fault is the stretch of the east branch fault(F5) of the Tangshan faulted zone which was triggered tectonics of the Tangshan earthquake in 1976.The developing of the Gulouzhuang ground fissures is enchanced by excavation collapse caused with small-scale coal mines.By the mechanics rule,the genetic mechanism of the Gulouzhuang ground fissures and its development trend are researched.
