摘要:

根据库伦公式确定地基土特征压应力σ_max 和地基土极限滑动剪切摩擦系数tgψ_max。改进基坑小型压板试验外荷载地基土强度σ_imax 和滑动剪切摩擦系数tgψ_imax，在σ_imax 和tgψ_imax 中具有位移和滑动两部分作用，研究滑动占有1/4 值。根据tgψ_imax 和tgψ_max 的大小比较，确定地基土和底板滑动形式和滑动安全系数。据此核对1968 年三河闸加固设计成果。

Abstract:

According to the coulomb formula, the characteristics stress σamx and the friction coefficient of the ultimate sliding shear tgψmax of foundation soil were detemrined.In order to improve the strength σima x and sliding shear friction coefficient tgψimax of foundation aldo, the external load and the sliding shear frictio n coefficient were improved, and two part functions of displacemnet and sliding were taken into account, so a s to study the slides accounted for a quarter of the value.Thel isding form and sliding safety factor of foundatio n soil and bottom plate were determined according to the compariosn of the size of tgψimax and tgψmax.Th e reinforcement design results of the Sanhe Sluice in 1968 were c hecked.
