摘要
以梯形沟槽埋涵为研究对象,建立沟埋涵洞的计算简图,利用内、外土柱压缩量相等的原则,形成等沉面高度的计算方法。研究表明,涵洞填土中的等沉面高度并非常量,洞顶填土高度大,等沉面高度小,填土高度不断增大,等沉面高度趋于定值;埋涵沟槽的底宽大、边坡缓,等沉面高度大。
A model of trapezoid trench buried culverts and a formulae to evaluate the the height of the plane of initial equalsettlement wrer proposed taking account of the effect of soil mass beside culverts.The study results show that The height of planeof equal settlement changes with the height of backfill.It decreases and comes close to a constant as the depth of backfill increased.The height of plane of equal settlement increases when the width of trench increases,the slope becomes gentle.
