摘要
20世纪60年代,某地修建提灌工程,采用了"减压仰斜式"挡土墙这种结构型式,至今仍在安全运行。由于结构新颖、合理、经济、安全,在当地逐步得到推广。但在力的计算方面存在许多不明确之处,依据库伦、朗肯基本理论,提出了各种力的解析计算。
In 1960s, ＂pressure-relief oblique＂retaining wall was used in a water- pumping irrigation works for the first time and it is still in safe operation. The retaining wall was generalized at the area for its rational structure, cost - effectiveness and safeness. However, there are still a lot of ambiguities in terms of the calculation of forces. Analytic calculation of various forces by Coulomb Theory and Rankine Theory is given.
