摘要

很多给排水、原油输送管道直接敷设于原状平面土基之上，此种情况下的管道基底压力分布明显不同于研究较多的其它类型基础上管道的分布规律。本文在工程现场试验的基础上，结合Winkler弹性地基解析法，初步探讨了平面土基上刚性圆管的基底压力的分布规律，由本文模型所得的计算结果与试验结果吻合程度较高。

Abstract

A large number of pipes are buried on flat soil foundation for supplying water or petrol. Its distribution of base pressure is apparently different from the one when pipes are buried on other foundations. Based on in-situ test data

a base pressure’s distribution law of rigid pipe on flat soil foundation is discussed with analytical method of Winkler elastic foundation. The computation model has been proved reasonable because of computation results tallying with in-situ test data. In-situ test results and the computation model can be used to compute pipes’ settlements and forecast their safety.
