| 摘 要： | 通过地球物理勘探和地下水动态研究,认为柏乡地裂缝主要是过量开采地下水引起的。过量开采地下水导致了该地区大面积的地面沉降,地层的差异沉降诱发了地裂缝;大量降水造成表层土软化,有些表层土随雨水流入下面的裂缝中,使地裂缝显现出来。

| Abstract: | Earth fissures occurs in Hengshui,Baixiang,Wen'an,Anping,Xianghe and Bazhou in Hebei Province in summer and autumn. The earth fissure at Baixiang at Xingtai is as long as 8km. This paper reveals that the Baixiang earth fissure was caused owing to groundwater overdrafts through general combination of geophysical exploration data and ground water level analysis. Over-extraction of groundwater had resulted in large-area land subsidence in this area. The difference in land subsidence occruing at both sides of t... |
