苏锡常地区地裂缝成因及预警

Formation mechanism and warning of earth fissures in Suzhou-Wuxi-Changzhou area

苏锡常地区地裂缝是我国地裂缝灾害最为严重的地区之一。地裂缝成因模式及机制非常独特且复杂,为了研究地裂缝成因,数十年来开展了大量的调查、钻探、槽探、物探等地质工作及物理模型试验工作。文章主要阐述了苏锡常地区地裂缝的成因模式、地裂缝的物理模型试验,以及采用多种先进技术方法的地裂缝监测工作,在此基础上,对苏锡常地裂缝的预警及防减灾工作也进行了合理化建议。

Suzhou-Wuxi-Changzhou(Su-Xi-Chang)area is one of the most serious earth fissure disasters in China.The genetic modes and formation mechanism of the earth fissures are very unique and complex. In order to study the genesis of earth fissures, a lot of geological works have been carried out for decades, such as investigation, drilling,trench exploration and geophysical exploration, as well as physical model testing. This paper mainly expounds the formation mode of earth fissures in Su-Xi-Chang area, the physical model testing of earth fissures, and the monitoring work of earth fissures using various advanced technology. Furthermore, reasonable suggestions is also made to the prevention and mitigation work of earth fissures in Su-Xi-Chang area.
