摘要
为评价埋地玻璃钢夹砂管涵洞的安全性,保障道路交通运输安全,本文以理论计算为基础,进行现场试验检测,综合分析地面车辆荷载和竖向土压力传至公路下的埋地玻璃钢纤维夹砂管上的作用力与管涵的受力变形特性,然后用回归预测模型计算1200 k N荷载下的力学参数值,验证管涵安全运营状况。结果表明,理论计算和现场试验进行比对,验证了车辆荷载作用下直径1.5 m、厚38 mm的玻璃钢夹砂管的安全可靠性,为玻璃钢夹砂管设计和施工提供科学理论依据。
For the evaluation of underground glass steel sand inclusion pipe culvert safety,ensure the safety of road traffic and transportation,according to the theoretical analysis as the foundation,field test method using,comprehensive analysis of ground vehicle load and the vertical soil pressure spread to highway of buried steel fiber glass sand inclusion tube of force and pipe culvert by force deformation characteristics,and then regression prediction calculation of values of the mechanical parameters of 1200 kN load model,verifying tube culvert operational safety. Results show that： theoretical calculation and field test are compared and verified the vehicle loads with a diameter of1. 5 and 38 mm thick glass reinforced plastic mortar pipe of safety and reliability,glass steel clip Sand pipe design to provide scientific theory basis.
