杨屯河地下涵洞进出口加固设计

杨屯河地下涵洞地处姚桥矿采煤区,采煤使杨屯地涵、大堤及上下游一定范围发生区域性沉陷,但地涵所受的曲率较小,地表移动基本上是缓慢下沉,不存在突陷性。根据具体情况,经过前期方案比较,现采用全加长方案进行布置和结构设计,将杨屯河大堤按20 a一遇的设防标准进行断面布置。

Strengthening Design of The Underground Culvert Access of Yangtun River

The underground culvert of Yantun River located at Yao Qiaocoal mine,the intersection of the training dike river which lies 1 500m to the east of Yantun town and Yantun river.Excavating coal result in the territorial downpunching of the underground culvert,the dike and a certain affected overburden during the upstream and the downstream.Because of its small curvature,basically the surface soil subsides slowly not suddenly.According to the concrete circumstance,expect the project to compare through front,now adopt to the all length project to arrange and structure design.The dike adopt to 20-year frequency standard to arrange the section.
