| 摘 要： | 根据某高层建筑深基坑护壁桩从实测钢筋应力求得的桩身变矩，用数值分析的方法，对桩侧土压力的分布和大小进行了反分析，所得结果与经典土压力理论有显差别，中用土拱的概念对桩侧土压力的分布进行了解释，并给出了桩侧土压力建议图式。

| Abstract: | Some numerical methods are presented for back-analysis of the earth pressure against the retaining pile for deep excavation by making use of the measured bending moments. The calculating results for one excavation case show that the distribution and value of the earth pressure above the excavation bottom on the retaining piles airs quite different from the classical Coulomb's or Rankine's earth pressure theory. The nonlinear distribution of earth pressure can be explained by means of soil arching theory. An earth pressure model is proposed. |
