Prestressing also increases the resistance to shear forces, and in some cases reduces the amount of reinforcement required to resist shear.

预应力也可以提高抗剪能力。在某些情况可以减少为了抗剪而需要的预加应力值。(没有听过为了提高抗剪加预应力的。能举个例子？，学习中)。

With the increase of the degree of compaction, the elastic modulus and the amount of reinforcement, the strength of reinforced soil increases.

加筋土的强度随着压实度、加筋层数及加筋材料弹性模量的增大而增大；

The parameters in the aeries include: amount of longitudinal reinforcement, amount of transverse reinforcement, shear span-to-depth ratio, thickness of tube wall and strength of concrete.

试验中的主要参数有：纵向钢筋的数量、横向配筋率、剪跨比、管壁的厚度及混凝土强度。
