双曲线切线模量法在铁路复合地基沉降计算中的应用

摘要

The calculation program of foundation settlement is established by using the C ＋ ＋ and VB computer langua- ges and based on the hyperbolic tangent modulus theory, and is verified for its applicability with a load test p - s curve of a railway composite foundation. The calculated results show that, the predicted settlements are well in agreement with those from load tests. This technique is a reasonable way to calculate or predict settlements of railway composite foundation.%基于双曲线切线模量法的理论基础，利用C＋＋语言和VB语言混合编程，编制了地基沉降计算程序，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。结果表明，计算值与实测值吻合较好，用于计算或预测铁路复合地基的沉降是一种比较理想的方法。
