Abstract Research purposes: The settlement of hish—speed railway must be strictly controlled，but it is very difficult to accurately calculate the foundation settlement in design of high—speed railway．In order to calculate the settlement of foundation accurately，a secant modulus method is offered through doing the indoor compression test on the basis of the existing research results．The final foundation settlement of railway is obtained by using the secant modulus method and the Bussinesq§solution．The verification shows this method is available and can be as the reference to the similar works．

Research conclusions: From the comparison of the calculation results obtained with the traditional layed summation method，the secant modulus method and the angle of spread method for one actual construction project，it was found the results obtained with the secant modulus method Was close to the actual foundation settlement．This indicates that the secant modulus method iS accurate and available．

Key words： compression test secent modulus Bussinesqg solution layed summation method
