SMP准则修正的土压力在上海中心大厦基坑的应用研究
|
摘要
本文给出了基于SMP准则修正的土压力在主动区、被动区以及不同水土分合算条件下的计算公式,与上海中心大厦基坑土压力实测数据和朗肯土压力计算结果进行对比,结果表明:相较于朗肯土压力,基于SMP准则修正的土压力与实测值更为吻合,且有一定的安全储备。
This paper presents the calculation formula of earth pressure based on SMP failure criteria in the active zone, passive zone, and different soil and water conditions. The calculation results based on SMP failure criteria of Shanghai Center Tower is compared with the measured data and the calculation results of Rankine's earth pressure. The results show that compared with that of Rankine's earth pressure, the earth pressure based on SMP failure criteria is more consistent with the measured value, and provides some safety margin.
