| 摘要: | 基于扰动状态概念理论, 提出了统一扰动函数, 并结合宁波轨道交通1号线和2号线的十字板剪切试验资料, 预测了扰动状态下的软土工程指标(如地基承载力、压缩模量等), 研究结果可为宁波软土工程勘察设计中受扰动的软土物理力学参数的取值提供指导. |
| Abstract: | In this research, the unified disturbance function is developed based on the Disturbed State Concept. According to reports on the first-stage vane shear test for the line 1 and line 2 in Ningbo rail transit, the engineering indices of soft clays, such as the foundation bearing capacity and compression modulus at disturbed state, have been predicted using the unified disturbance function. The study results may serve as the scientific references for determining the physical and mechanical parameters of soft clay under the disturbed state for the geotechnical investigation and design |
