wedge effect

Study on effect factors of end concavity in cross wedge rolling

楔横轧轧件端头凹心影响因素的研究

With the sliding wedge sliding down, the gravity of sliding body generates pushing effect on the soil of both sides. As a result, there is no crack observed at deep place.

滑动楔形体向下滑动的同时，滑动体自重力对两侧土体产生推挤作用，深部实际破坏面不会张开。

Based on the arching effect of soil mass, a schematic diagram for the calculation of the balancing arch of sliding soil mass in the form of a wedge at the back of a retaining wall is presented in this paper;

本文根据土体中存在拱效应这一事实，给出一个挡土墙背填土滑裂体平衡拱的计算图形。

The analysis shows that when loading rate is slow the free water in crack may reach the tip and the wedge effect of water accelerates the expansion of the crack causing the reduction of concrete strength.

分析认为，慢速加载时，裂纹中的自由水可以达到缝尖，自由水的楔入作用加速了裂纹的扩展，降低了混凝土的强度；
