中文摘要：本文对陈希哲和叶菁编著的《土力学地基基础》(第5版)教材,填土表面作用均布荷载库伦土压力计算的内容进行了分析,认为教材在计算虚构填土的高度时存在问题,并分两种情况对教材存中的问题提出修改意见:(1)保留原图,把虚构填土高度修改为q/γcosβ;(2)修改教材中的计算图,把垂直填土表面的均布荷载改为竖向均布荷载。在此基础上,对教材中推导过程提出了优化建议,给出了推导虚构挡土墙高度更为简明方法。

外文摘要：Analyzing the Coulomp＇s active earth pressure calculationof backfill with inclined surface under uniform load in thetextbook of ＂Soil Mechanics and Geotechnical Engineering＂ （fifthedition） compiled by Chen Xizhe and Ye Jing, the authors pointout existing a problem to calculate the imaginary depth of fill inthe textbook and put forward suggestions for revision. （1） Retainingthe figure in the textbook and revised the formula of theimaginary depth of fill, h＇= q/γcosβ. （2） Revising the figure in thetextbook. It needs to change the uniform load vertical to the inclinedsurface of back fill into the vertical downward load. On thisbasis, we raise suggestions to optimize the derivation of the imaginarydepth of the retaining wall and provide a more concisederivation to calculate the imaginary depth of the retaining wall.
