摘要

本文介绍的是四川省黑水县芦花沟泥石流拦砂坝溢流口防止冲刷的一种钢件结构设施。其结构型式是:在拦砂坝溢流口下游侧底面与下游坝体垂直临空面交接处

用8-10毫米的钢板作成

伸出下游临空面59厘米

高出溢流口底面10-15厘米的钢件

用φ25毫米的螺纹钢筋焊接后

再在坝体溢流口浇筑50厘米厚的200号钢筋混凝土

使其与拦砂坝衔接成整体。有这种设施的溢流口

能拦蓄一层泥石流

起消能和缓冲作用。在后来的泥石流过坝时

将泥石流对坝体溢流口直接的冲刷、摩擦、碰撞和淘蚀作用的外力

变成泥石流内部的石磨石、砂磨砂的内力

从而保护拦砂坝溢流口不被过坝泥石流所破坏。

Abstract

This paper describes an innovative steel structure and installations forscouring prevention adopted in the spillway of the debris flow controlproject in Luhua Ravine of Heishui county

Sichuan province. The struc-ture is designed as

at the joint of lateral bottom and air face downstream the spillway of check dam

a 8-rocm thick steel plate was used to make a steel part which extrends out 50cm from the downstream air faceand rises 10-15cm

welded on double threading steel bar 25mm in diame-ter

it was casted into a steel bar-reinforced stopper

No. 200 in 50cm

connected with the check dam as a whole. Check dams with a spillwaystructured in this way can retain a layer of debris flow and play a role ofenergy dissipation and cushioning. When the following debris flows cro-ss the dam

the external force of direct scouring

friction

impact andundercut exerted on the dam by debris flow would be transformed intothe inner stress of stone against stone and sand against sand inside deb-ris flow

thus protecting the dam outled from the damage by debris flowwhich would cause the destruction of the whole dam.
