| 摘 要： | 在桩－网复合地基中,如何结算“网－桩－土”体系的共同作用而计算其沉降量,是一个值得研究的新问题,目前国内外均没有合适的计算方法。本文的新思路是：以平板模拟网单元,基于薄板大挠度变形理论,结合桩－网复合地基的具体情况,提出路基工后沉降量的直线计算方法,并给出工程算例。分析表明,本文计算方法具有合理性和适用性。

| Abstract: | In the pile net composite foundation, a new problem of studying how to consider the function of the net to calculate its settlement is worth to be investigated. In this paper, the form and working mechanism of the pile net composite foundation was discussed. Under the common work of the "pile net soil" system used sheet to simulate net unit, the calculating method of subgrade residual settlement was deduced basing on the sheet deformation theory. Engineering example is given. |
