软土地区混凝土检查井壁厚计算法

Calculating Method for Wall Thickness of Concrete Manhole in Soft Soil Area

该文针对软土地区混凝土检查井的特点,提出采用板壳理论对混凝土检查井壁厚进行计算,推导出检查井壁厚计算的精确解,通过天津开发区南海路工程验证表明,采用该方法设计的检查井可满足工程需要,避免了工程的浪费。软土地区大型检查井壁厚薄壁壳解,为城市道路检查井壁厚计算提供了一种思路,可供类似工程参考。

Based on the characteristics of the concrete manhole in the soft soil area, the article puts forward the use of plate shell theory to calculate the wall thickness of concrete manhole, deduces the exactitude solution of calculating the wall thickness of manhole. Through the validation of Tianjin Development Area Nanhai Road Project, the manhole designed by this method can meet the engineering demands and avoid the waste of the project. The thin wall shell solution of the wall thickness for the large sized manhole in the soft soil area provides a thinking of calculating the wall thickness of the urban road manhole able to be referred for the similar projects.
