透水砖地面结构排水系统的计算与应用

透水砖铺装地面是“海绵城市”建设的重要方式。土壤的透水系数和地下水位情况的不同,要求透水砖地面结构层对下渗雨水具有渗、蓄、排的不同功能。通过总结各类透水砖地面结构排水系统的计算公式和工程实例的应用,说明了该系统的具体应用场合,并提出了多专业协同进行透水砖地面设计与应用的建议。

Calculation and Application of Drainage System of Permeable Brick Pavement Structure

Permeable brick pavement is an important way to build"sponge city".Due to the difference between the permeation coefficient of soil and the condition of underground water level,it is required that the permeable brick pavement structural layer has the different functions of permeation,storage and drainage of infiltrated rainwater.By summarizing the computational formulas of various permeable brick structural drainage systems and the application of engineering cases,the detailed applications are explained,and the suggestions on the design and application of permeable bridge pavement with the multi-specialty coordination are put forward.
