重力式挡土墙广泛应用于公路工程和其它工程中,由于计算工作量大,设计中通常套用定型图或查表计算。但是,实际工程的设计参数与定型图往往不尽相符,致使设计近似程度较大,影响测设质量的提高。在公路设计手册《路基》中,用了一百余页的篇幅,编制了“破裂角θ及主动土压力系数K值表”和“常用重力式石砌挡土墙截面尺寸参考表”,也不能满足实际工程中荷载、填料、墙体和地基等物理力学指标的不同情况。为了尽快推广应用微型计算机,本文应用PC-1500袖珍计算机,编制了重力式挡土墙设计计算程序。
Gravity retaining wall is widely used in highway engineering and other projects, due to the large workload, the design is usually applied stereotypes or look-up table calculation. However, the actual engineering design parameters and stereotypes are often not consistent, resulting in a larger approximation of the design, affecting the improvement of the test set quality. In the highway design manual “Subgrade”, with a length of more than 100 pages, “Cracking angle θ and active earth pressure coefficient K value table” and “reference table of common gravity stone retaining wall cross-section size” are also prepared. Can not meet the actual project load, filler, wall and foundation and other physical and mechanical indicators of different situations. In order to popularize and apply the microcomputer as soon as possible, this paper applies the PC-1500 pocket computer to compile the gravity retaining wall design and calculation program.
