摘要
针对哈尔滨市区地面沉降特点,根据地面沉降痕迹调查,利用岩土工程勘察规范中的“分层总和”法,分别对两个漏斗中心重型机器厂和菅草岭的沉降量进行计算。结果表明,不同的释水厚度、不同的表层黏性土厚度所产生的地面沉降量亦有所不同。到2000年哈尔滨市区两漏斗中心沉降量分别达15.38cm和6.69cm。
Aiming at characteristics of land subsidence in Harbin City,based on investigation of settlement traces, the author used the layerwise summation method from the Rock Soil Engineering Reconnaissance Specification to calculate settling volumes of two infundibulum center regions, where are the Heavy Machinery Plant and Jiancaoling Town. The results show that different thicknesses of released water and various argillaceous thicknesses produce different settling volumes. The settting volumes of two infundibulum center regions in Harbin City are 15.38 cm and 6.69 cm in 2000, respectively.
