長久以来未能完满解决的,俯斜擋土墙上压力计算方法問題,目前已为我国铁道科学院、唐山铁道学院和铁路专业設計院等单位共同解决了,提出了一套较为完善的新方法,並得到今年七月召开的“擋土墙設計理论研究”第二次会议確定。推广试用。新方法由两組公式組成:(詳見铁路专业設計院唐山铁道学院合編的“衡重式路堤擋土墙上墙土压力簡化計算方法的研究”)。①確定第二破裂面位置的破裂角公式。②求解第二破裂面最大水平土压力公式。这些公式,比较精確而又簡便地解决了俯斜擋土墙土压力計算的問題。它的突出特点是:精確、简便、适用范围广。
For a long time failed to satisfactorily solve the pressure on the retaining wall of the method of calculation, has now been China Railway Academy of Sciences, Tangshan Railway Institute and Railway Design Institute and other units jointly solve, put forward a set of more perfect new method, And was held in July this year, “retaining wall design theory,” the second meeting to determine. Promote the trial. The new method is made up of two sets of formulas: (See “A Simplified Calculation Method of Earth Pressure on the Wall of Weighing Type Embankment” compiled by the Railway Engineering Design Institute, Tangshan Railway Institute). ① determine the rupture angle of the second rupture surface formula. ② Solve the second largest earth surface pressure formula of rupture plane. These formulas solve the problem of earth pressure calculation of the inclined retaining wall more accurately and simply. Its outstanding features are: accurate, simple, wide range of applications.
