| 摘 要： | 采用室内试验求取的压缩性指标,由于受样品扰动的影响,往往不能反映实际土体的变形特点.为了寻求一种合理确定压缩性指标的方法,根据目前实际中广泛采用的沉降量计算公式,以深港西部通道填海工程软土的实测沉降量为例,通过对沉降量计算公式中参数的合理选取,反算求得了压缩性指标,经验证,其结果符合实际情况.

| Abstract: | Because the soil sample in indoor test is disturbed,the index of compressibility cannot reflect the deformation properties of practical soil mass. In order to find a reasonable means to determine the index of compressibility,a reasonable selection of parameters in the settlement formula is made on the basis of common settlement formula in present practice and the practical settlement value from the soft clay of westem channels of Shenzhen lough filling engieering. Then the index of compressibility is obtained and calculated. The result is proved in accordance with the actual situation. |
