路表排水泄水口设计合理性的验核方法

Method for Verifying the Reasonableness of Pavement Surface Drainage Design

针对现行高速公路路表排水泄水口设计中存在的一些问题 ,本文提出了应结合高速公路各路段的纵坡、横坡以及降雨强度等实际状况 ,对现行设计进行验证复核的必要性 ,并按照公路路表的实际排水过程 ,描述了泄水口的泄水规律 ,推导了路段上泄水口数量的合理计算式 ,并特别给出了在两相邻纵坡之间增布泄水口的设计计算方法 。

For there are some problems in design of drainage gap on highway surface, necessity for verifying the reasonableness of present design of drainage is suggested on the basis of considering the practical factors such as longitude slope, transverse slope, rain density and etc of every section of highway According to actual process of draining on highway surface, the draining law of drainage gap is described, the formulas for calculating the amount of drainage gap are also deduced, and the method of design and calculation is presented particularly for adding drainage gaps among two adjacent section of longitude slope in highway, which would be references to the design of drainage on highway surface
