摘要:
吹填软土由于其物质成分和沉积环境千差万别,决定了其工程性质也差别很大,具有区域性特点。本文以大型沉降柱模拟吹填泥浆自然沉积,对天津滨海新区吹填泥浆静水沉降过程中泥水分界面、含水量、孔隙比变化及其沉积后的相关特性进行了探讨,并对其微观结构特征进行了研究。试验结果分析表明:天津吹填土富含粘土矿物,微结构不稳定。在沉积过程中,颗粒分选明显,各项指标前期变化大,后期趋于稳定,总体工程性质差,难以直接满足工程建设的需要,需进行相应的处理。
Abstract:
Due to the different material composition and depositional environments,the engineering properties of soft dredger soil varied widely and also has regional characteristics.In order to probe the mud-water interface,water content and void ratio changes in the procession of subsidence and post-depositional characteristics of Tianjin soft dredger soil,the large-scale settlement column is designed to simulate the natural sediment of the mud,and its micro-structure is also studied.The test results sho...
