土拱效应能够调节探究桩网复合地基中桩顶的预应力和沉降。本文针对实际情况下的土拱效应的发展变化规律进行单桩数值模拟和数学解析，根据荷载下复合地基的荷载传递机理及变形特征，综合考虑路堤填土的土拱效应和桩、土的荷载传递性状。
土拱效應能夠調節探究樁網複閤地基中樁頂的預應力和沉降。本文針對實際情況下的土拱效應的髮展變化規律進行單樁數值模擬和數學解析，根據荷載下複閤地基的荷載傳遞機理及變形特徵，綜閤攷慮路隄填土的土拱效應和樁、土的荷載傳遞性狀。

Soil arching effect can regulate and inquiry the prestress and set lement of pile block in net composite fou-ndation. This article in view of the actual situation of the development changing rule of the soil arch effect makes nu-merical simulation and mathematical analysis of the single pi-le, according to the transfermechanism and deformation char-acteristics of the composite foundation under the load of lo-ad, considers the load transfer of embankment soil arching ef-fectand, pile and soil properties.
