摘要
基于土的塑性上限理论,结合桩间土的成拱效应,假设了土体的三维破坏模式,推导出作用在桩上土压力上限解,并与朗肯土压力计算结果进行了对比分析。
An earth pressure calculation mormula is deduced based on the soil plasticity upper-bound theory when three-dimensional failure modal is assumed by the arching effect in soil of pile separation. And the calculation result is analyzed comparing with those of Rankine＇ s earth pressure.
