英文摘要	Research on the performance of pile for the weak or non-collapsible Q2 Lishi loess layer is very scarce. In order to determine the pile Q2 Lishi loess layer thickness on the large pile in loess area, the single pile static load test was carried out. Concrete strain gauges and reinforcement stress meter are arranged on test piles, and soil pressure cells were installed on pile bottom to test internal forces on-site. Results show that:(1) Distribution of axial force of pile and lateral friction along the pile is not only related to pile top load, but also related to the nature of pile side soil. (2) When the ratio of pile top load and limit value of pile top load is less than 0.80(Pt/Put/Pu≥0.80, endpoint soil subsidence Sb should be considered when calculating the pile settlement. (3) Standardized coefficient of the simplified method of synthetic factor ζ value slants big, it is recommended to take ζ = 0.44 in the region of the same type as the pile of calculation parameters. A new way was put forward by using amount of pile body compression to estimate the settlement of single pile in terms of simplified method and linear method. ©, 2014, Academia Sinica.
