摘　　要：变刚度群桩基础在我国还是一种新形式,其沉降计算方法未见于规范。在5组物理模拟试验的基础上,对试验数据进行回归分析,得到变刚度群桩基础沉降的计算公式,并以河南发展大厦为例,用相似模拟法则对其进行了沉降预测分析。结果表明,本文方法要比《建筑桩基技术规范》更接近实际。Varying rigidity pile group is a new form in our country whose settlement calculating method has not been found in the code. This paper has got a method to calculate the settlement of varying rigidity piles by regression analysis on the base of test data in 5 teams. The settlement of henanfazhan building has been forecasted according to similar simulated theory with the result of regression equations. The result indicates that the method is more approach fact than 《Technical code for building pile foundation》.
