摘要
根据宁波地区120余项实际工程的勘察资料,从地质成因、颗粒级配、矿物成分、土性指标、微观结构及结构性等方面系统分析了宁波海相软土的工程特性,并与我国沿海典型软土进行了比较。选取宁波地区典型软土,通过室内试验,从内因和外因两方面分析研究了含水量、干密度、围压、应力路径、排水条件以及剪切速率等因素对应力应变曲线的影响。宁波海相软土工程特性研究对该区今后的工程建设具有实际意义。
Based on the statistical data of 120 works in Ningbo, geological origin, mechanical composition, mineralogical composition, soil indicators, micro-structure and structural feature of Ningbo marine soft clay were studied, and were compared with other coastal soft clays. By triaxial compression test for typical Ningbo soft clay, the influence of water content, dry density, confining pressure, stress path, drainage condition and shear rate on relation curve between stress and strain was analyzed from internal cause and external cause. Some useful conclusions are also obtained in the paper. Studies on engineering properties of Ningbo marine soft clay will provide instructions for future constructions.
