摘要：
According to the mechanical theory, this paper deduces the dynamic relationship between settlement and temporal variation in void ratio under large-area loading. The in-situ e-t curves and e-p curves of hydraulic fill in the process of drainage consolidation are inverted with the observed data of telescoping tube settlement gauge pre-buried in hydraulic fill. Based on the e-t and e-p curves of the drainage consolidation project of the Nanitang Pond in West Port Area, Shenzhen City, the following conclusions are drawn through the analysis: (1) In the process of preloading, the soil at the edge of the hydraulic fill is subjected to the uneven load and the stress of soil. Initially, the soil undergoes the perturbation-compression process; As the soil consolidates, the disturbance gradually attenuates and the soil structure weakens; (2) In the process of preloading, the nearer to the load center the soil is, the more uniform the load it bears, and the closer the e-p curve is to that of the lab soil tests. Therefore, the e-t and e-p curves of the observation point in the load center best represent the pore change characteristics of hydraulic fill; (3) The temporal and pressure-induced variation in the average void ratio of hydraulic fill at each observation point is approximately consistent with that of the observation points near the middle section of the layer. The central observation point is the most typical position to demonstrate the void ratio variation law of the middle section.

摘要：
Based on the theory of shear displacement method, the transfer matrix of pile in layered soils was deduced, so the analytical theory of settlement of single pile in layered soils is established, which can take into account the nonlinear influence of soils, and with which settlement, distribution of axial force, displacement and skin resistance of single pile along the depth in layered soils can be easily attained. By contrast with the practically measure data, it can be seen that the method proposed in this paper is simply and comparatively accurate in calculating the pile settlement under working load.
