中文摘要:

研究了山西省清徐县平泉村一武家坡村地裂缝地质灾害的现状和主要特征。清徐县平泉村至武家坡村等7个村庄自2002年春天出现地裂缝以来,其灾害呈现日趋加重的趋势,给当地村民的生产及生活带来了极大影响。经过对平泉村至武家坡村地裂缝的现场实地调查,认为清徐县平泉村一武家坡村地裂缝的分布情况复杂,影响带的宽度从3m左右到100多米不等,凡位于地裂缝带内的大部分建筑物都遭到了破坏。地裂缝带内的地面变形形式有陡降型和缓降型两类,其中位于陡降型变形带上的建筑物破坏最为严重。地裂缝引起建筑物的破坏主要有墙体开裂、地面倾斜、地基下沉、楼梯断裂、门窗变形等多种形式。清徐地裂缝目前仍处于活动阶段,这种活动趋势还将持续一段时间,建议地裂缝带内的村民应尽快搬迁,并限制其在地裂缝带内的工程活动,以免造成更大的损失。

英文摘要:

The situation and main characteristics of geological disaster due to a ground fissure are studied. The ground fissure is located between Pingquan Village and Wujiapo Village in Qingxu County. Founded since 2002, the hazards have become severer and severer and these seven villages have suffered from the ground fissure. By field investigating to the ground fissure, it is concluded that the distribution of the ground fissure is complex. It is found that the effect - zone width is various from 3 meters to 100 meters. Most buildings in the ground fissure zone were destroyed. In the zone, land deformations are shown as steep drop type and slow drop type, and the buildings within steep drop type zone were destroyed seriously. The destroy forms are shown as wall crack, ground surface tilt, foundation sink, stair fracture, window and door deformation, etc. The ground fissure is activating and will last for some time. It is suggested that the villagers in the zone move out as quickly as possible, and any engineering activity be restricted to avoid more loss.
