近几年来无锡县东亭镇部分村舍发生房裂、地裂等灾害。研究表明,过量抽取地下水引起地面沉降是产生地裂缝的背景因素;裂缝区第四系覆盖层以下的古陡坡地形是张应力集中区、其上方易先产生不均匀沉降;裂缝区不均匀分布的软弱土层是使房裂地裂发育的直接原因。
In recent years, part of the village in Dongting Town, Wuxi County, occurred cracks, cracking and other disasters. The results show that ground subsidence caused by over-pumping groundwater is the background factor of ground fissure. The ancient steep slope below the Quaternary overburden in the fracture zone is a stress-concentration zone, and the uneven settlement is easy to occur above the zone; The weak soil is the direct cause of the development of the cracked earthquakes.
