层状构造土的工程地质特征分析

Analysis of Engineering Geologic Characteristics of Stratified Structural Soil

由于层状构造土的层状特性,使土质各向异性的特征更加突出,给获取层状构造土物理力学指标及评价其固结沉降、承载能力带来困难,进而影响港工建筑物基础的选择。以某工程勘察为例,分析层状构造土的成因、分布规律及其承载能力等工程地质问题,提出对今后此类工程勘察的一些意见和建议。

The stratiform features of stratified structural soil make its anisotropic characteristics more prominent and make it difficult to obtain the physical and mechanical properties of stratified structural soil and to evaluate its consolidated settlement and bearing capacity,thus affecting the selection of foundations for maritime structures. Taking the geotechnical investigation on a project for example,the cause of formation,pattern of distribution and bearing capacity of stratified structural soil as well as other engineering geologic problems are analyzed and some comments and recommendations are made for similar geotechnical investigations in future.
