吹填土静力触探测试及主要特性分析
摘要:天津滨海新区吹填土在形成过程中受重力分选作用及水动力条件影响,加上后期真空固结方法处理,使其工程性质复杂。采用静力触探原位测试手段,通过对实测参数的统计、分析,综合考虑野外钻探编录及室内土工试验结果,将吹填土分为硬壳层、软弱粘性土层及底部砂性土层3个工程地质层。顶部硬壳层及底部砂性土层强度相对较好、层位分布不稳定,软弱粘性土层具有强度低、压缩性高的软土工程特性。吹填土在排水口部位以软弱粘性土层为主,工程性质相对其他部位差。
Abstract:Effecting by the action of gravity hydrodynamic force and improving through the vacuum consolidition way, the dredger fill of Tianjin Binhai New Area has more complex engineering properties. Through the cone penetration test(CPT) and other way, it can be divided into Hard shell soil, Weak Clay soil and Sand soil, All together, three strata from top to bottom. The Hard shell soil on the top and sandy soil in the bottom consist high intensity, unsteadable distribution characters. Just as the soft soil, low intensity and high compressibility is the main characters of Weak Clay soil. The Dredger fill near the Water outlet, which is mainly composed by Weak Clay soil, has poor engineering properties.
