摘要

顶进箱涵全断面置换管幕工法是在出发井和接收井之间，利用顶管法在箱涵所在位置顶推钢管，置换出土体，形成全断面管撑，再顶推箱涵，同步置换出已顶进的钢管。针对该工法中的钢管幕，建立其内力和变形计算简化模型，将钢管视为在附加荷载作用下的置于Winkler地基上的弹性地基梁，推导出全断面管幕形式顶进箱涵置换管幕工法的钢管幕内力和变形计算公式，以此分析钢管幕的竖向变形。并采用弹性地基梁法和模拟试验比拟法，发现二者在规律及大小上都较为接近，说明所推导出的内力和变形计算公式具有一定的合理性，为实际工程的设计提供了理论依据

Abstract

In box culvert jacking and replacement full face pipe-roof method

steel pipes are jacked between the start well and the receiving well. Soil in the pipes is excavated and the full face pipe-roof forms the shape of the box culvert. Subsequently

box culvert is jacked and replaces the full face pipe-roof. Specific to the pipe-roof which is considered to be an elastic foundation beam

two mechanical calculation models of the pipe-roof are built; the deflection curve equation of pipe-roof and the relating settlement control conditional derivation equation can apply to analyze the vertical deformation. By using the elastic foundation method and the simulation test analogy method

it is found that the calculation result is similar to the test result

which means the deflection curve equation is rational and provides theoretical basis for real projects.
