强夯含块石人工填土地基不存在明显的分层现象,因此,采用分层总法和规范法计算出的地基沉降量与实际相差很大。本文根据强夯含块石人工填土地基随深度不同密实度不断变化的特点,结合Rayleigh波波速与压缩模量之间的关系,提出强夯含块石人工填土地基沉降量计算的新方法。这种计算方法是基于应力、压缩模量与深度的微分关系,通过沿深度积分来计算地基沉降量,并将这种计算方法应用于某变电站强夯含块石人工填土地基沉降量计算中,以满足工程实际中的迫切需要。
There is no obvious stratification phenomenon in the dynamic compaction block-filled artificial ground, therefore, the settlement calculated by the stratified total method and the standard method is quite different from the actual. In this paper, based on the characteristics that the dynamic compaction of artificial ground filled with rockfill varies with the depth of different compaction depth and the relationship between the wave velocity and compressive modulus of Rayleigh wave, a new method to calculate the settlement of dynamic compaction embankment artificial ground is proposed . The calculation method is based on the differential relationship between stress, compressive modulus and depth. The ground settlement is calculated by integrating along the depth. The calculation method is applied to the settlement calculation of the ground filled rock mass with artificial stone in a substation In order to meet the urgent needs in engineering practice.
