摘 要: | 从经典固结理论出发,通过对某直排式真空预压软基处理工程实测数据进行沉降速率分析,对沉降速率的控制标准进行探讨,提出不同地质条件下的软基处理采用的沉降速率控制标准不同。尽管沉降速率超过《港口工程规范》的控制标准,但处理后软基是稳定的。

Discussion on Control Standard of Settlement Rate of Straight-line Vacuum Preloading Soft Foundation Treatment |
| |
Abstract: | Base on the classic consolidation theory, the settlement rate is analyzed through the measured data of a straight-line vacuum preloading soft foundation treatment, the control standard of settlement rate is discussed and the settlement rate control standards used in soft foundation treatment under different geological conditions are proposed. Although the settlement rate exceeds the control standard of Port Engineering Code, the soft foundation after treatment is stable. |
