摘要
分析了综合管廊设防水位的确定方法。结合管廊结构特点,考虑了管廊侧壁摩阻力,研究在不同地下水位下管廊所受水浮力与计算方法,并进行工程抗浮算例验证,研究结果可为抗浮设计提供参考。
The method ascertaining the water level for prevention of up-floating was analyzed. Combining the structure characteristic of utility tunnel and considering the side friction of utility tunnel, the buoyancy of water and computation method were studied, and the example of engineering anti-floating was checked. The research results can provide references for anti-floating design of utility tunnel.
