摘　　要：组合式挡墙的基坑围护能够充分发挥各种型式挡土墙的优点 ,使基坑围护既安全又经济。本文提出组合式挡墙的基坑围护非线性的空间设计计算理论和方法。工程实例的计算和分析表明 ,采用这种计算方法计算得到的结果符合实际情况 ,而计算时间又短 。The support structure of combined retaining wall can get the utmost out of various retaining walls. A nonlinear space computation method for combined support structures is proposed in the paper. The idea is to divide the retaining walls in two?direction. The behaviors of retaining wall just like space grids. In the vertical direction, the retaining wall can be modeled as many vertical cantilever beams. In the horizontal, the retaining wall is modeled as many horizontal curve beams. The interaction of two?direction beams is completed by the consistant of displacements at those connected nodes. At same time, the nonlinear relationship between the earth pressure and displacements is considered. The computation and analysis of engineering examples are shown that the results obtained by the method are nearly the same as the results of an actual measurement.
