在国内,尚未见弹塑性地基模型用于研究高层建筑与地基的共同作用的报导。本文最初旨在探索上海粉砂土弹塑性模型能否用在高层建筑与地基的共同作用,经过增量法的计算结果和类似地基的实测结果相比,足以表明,该模型在一些简化假定的条件下,可以分析地基与高层建筑箱形基础的共同作用,求得的地基反力和沉降与类似地基的实测结果比较接近;本模型的地基反力分布规律与弹性半无限地基模型有本质上的区别。
In China, no elasto-plastic foundation model has been used to report on the joint action of high-rise buildings and foundations. The purpose of this paper was initially to explore whether the elasto-plastic model of silty sand in Shanghai can be used in conjunction with high-rise buildings and foundations. Comparing the results of the incremental method with the measured results of similar foundations, it is sufficient to show that the model is based on some simplifying assumptions. Under the conditions, the interaction between the foundation and the high-rise building box foundation can be analyzed. The ground reaction force and settlement obtained are similar to the measured results of similar foundations; the distribution law of the foundation reaction force and the elastic semi-infinite foundation model are essentially The difference.
