摘要
软土成因的地质与水文环境、物质因素和结构性因素等区域特性共同决定其不良工程特性,通过对珠江三角洲软土分布特征的调查研究及软土成因的地质与水文环境分析,发现珠江三角洲软土分布广泛,其沉积呈现阶段性和多样性特点,与长江三角洲一带软土相比,因其独特的江水与海潮复杂交替的地质、地理成因形成软土的区域性特性,使其成为全国工程报道过的最软软土,在软基加固时应区别对待。
Regional characteristics of soft soil genesis such as geological and hydrological environment,material factors and structural factors determine its bad engineering properties,through the study of distribution characteristics of the pearl river delta soft soil and geological and hydrological environment of the soft soil origin,found that soft soil is widely distributed in the Pearl River Delta and its sedimentary present periodic and diversity characteristics. Compared with the Yangtze River Delta soft soil,because of its unique geological and geographical origin of river and the sea complex alternate form the regional features of soft soil,making it become the most soft soil reported in national engineering which should be treated differently in soft foundation reinforcement.
