钢筋插筋土中钢筋的抗剪作用

本文在综合分析插筋补强土体剪切试验基础上，参考横向受力桩所受剪切力的计算方法，提出了用于评价插筋横向抗剪作用及其产生的补强效果的理论计算方法；并据此计算方法对试验条件下插筋在变形不连续面位置的剪力及由此剪力产生的抗剪补强效果进行了计算；然后将计算结果与试验的实测结果进行了分析对比，结果表明理论计算方法在一定的土体变形范围具有良好的精度和适用性。本文也对插筋的抗拉作用效果和抗剪作用效果从理论和试验两方面进行了分析。

Function of the Lateral Resistance of Steel Bars in Earth-Reinforcement

Based on the results from a series of simple shear tests for simulation a reinforced cut -- off slope with steelbars, this paper proposes a calculation method to evaluate the shear resistance and effect of the reinforcing materialsinvoking the theory of the lateral resistance of foundation pile. It is shown by the comparison between data obtainedfrom calculation and tests that the calculation method is highly effective until large shearing displacements appear.The role of both tensil force and shear force in reinforcing materials is also discussed based on the results ofcalculation and tests.
