摘要
本文从分析塌陷机理出发,按照地下水位在疏干过程中的时空关系,把岩溶地面塌陷分为瞬发性和迟后性两种塌陷类型。论述了塌陷形成条件、特征与其土质性质、结构的关系。根据湖南169厂塌陷的形成条件,提出了一种迟后性塌陷综合防治途径和方法。通过该厂近五年的治理实践,证明是成功的。
Based on analysis of the mechanism of surface collapses, the paper divided collapse into the instantaneous and the delayed collapse by the change of water table during dewatering. The relationship between the condition of collapse development and the soil property and texture is expounded.
A comprehensive preventing method is presented for the delayed collapse in the 169 Factory, in Hunan. After practice for 5 years, it is evident that the method is effective and succesful.
