摘　　要：为了对工程施工提供合理的参数,基于室内土工试验和常规三轴试验,选取佛山禅城地区四种浅层典型岩土体:淤泥、淤泥质土、粉质黏土、全风化粉砂岩,对其进行试验研究,获得包括天然含水率、天然密度、塑限、液限、孔隙比等物理力学性质指标,再通过室内常规三轴试验,获得四种岩土体应力应变关系曲线,为后续针对该地区的工程地质条件研究以及建筑施工提供参考。To provide reasonable parameters for engineering construction,based on indoor geotechnical test and conventional triaxial test,we select four kinds of typical shallow soil and rocks in Chancheng of Foshan:silt,mucky soil,silty clay,and completely weathered siltstone.By carrying out Experimental study on them,the natural moisture content,the density of natural,plastic limit,liquid limit,void ratio,etc.are obtained,which are the indices of physical and mechanical proper-ties,then through the conventional triaxial test in laboratory,we attain four kinds of stress-strain relationship curve of rock and soil,which provides a reference for the subsequent study of engi-neering geological conditions and construction in this area.
