摘要: 为揭示山区公路桥梁结合部位水毁规律、明确水毁主要原因、完善水毁防治技术,开展无防水毁、浆砌片石和石笼围堰3种工况下的水毁防治模型试验。测定水流流速、水毁堆积物厚度及水毁掏空深度,确认水毁堆积物厚度、掏空深度、水流流速三者与水毁冲刷时间之间的关系。研究表明:无防水毁工况下,模型完全毁坏,其冲刷毁坏过程是渐进的,且有显著的阶段性,水毁堆积物形态以竖直向和水平向堆积物厚度表征;浆砌片石和石笼围堰防水毁工况下,模型完好。

Abstract: In order to reveal flood damage rule, make clear the main causes of flood damage and improve the flood damage prevention and cure technical measures for highway-bridge binding site in a mountainous area, model tests were carried out under 3 working conditions, without prevention and cure measures, adding mortar rubble, and adding stone cage cofferdam to the site. The water flow velocity, the flood damage accumulations' thickness and the flood damage dig depth were measured. Relationships between the flood danmage scour time and the flood damage accumulations' thickness, dig depth and the water flow velocity were established. Research shows that under the working condition of without prevention and cure measures, the model is destroyed completely, the erosion and destruction progress step by step and with significant stages, and the flood damage accumulations' form is characterized by accumulations' thickness in vertical and horizontal direction, that under the working conditions of mortar rubble and stone cage cofferdam prevention and cure, the model tested is intact.

Key words: highway-bridge, mortar rubble, stone cage cofferdam, model test, highway-birdge binding site, flood damage
