摘要
研究目的:如何准确而又简便地计算与预测地基沉降是工程实践中一直未能很好解决的问题。在简要分析双曲线切线模量法的理论基础上,利用C++和VB语言混合编程,编制基于载荷试验的双曲线切线模量法的地基沉降计算程序,并利用某铁路复合路基载荷试验p～s曲线进行计算以验证其适用性。研究结论:双曲线切线模量法用于预测客运专线无砟轨道铁路路基沉降具有比较高的精确度,能够将沉降预测的时间提前到路堤填土施工前,是对目前客运专线无砟轨道铁路路基沉降计算与预测方法的补充。
Research purposes： How to calculate soil foundation settlement simply as well as accurately is still an issue not well resolved in engineering design. The calculation program of foundation settlement was written by using the C ＋ ＋ and VB computer languages based on the hyperbolic curve tangent modulus theoretical basis. Then, a load test p - s curve of a railway composite foundation was calculated to verify its applicability. Research conclusions ：The calculated results show that, the hyperbolic tangent modulus method presented in this paper has high accuracy in predicting the settlement of passenger ahead of time before construction. This technique may be railway composite foundation. dedicated railway composite foundation, and it can forcast potential to calculate settlements of passenger dedicated railway composite foundation.
