在富水砂层修建城市地下过街道的施工技术

根据城市地下工程特点，结合武汉市在富水砂层中修建的地下过街道实例，分析了地面降水所采取的降水方案，同时，也对本工程深井降水对地表、周围建筑物沉降做了全面的观察分析，观察结果分析表明，该方案能充分满足工程需要。

Construction Technology of City Underground Pass in Rich Water Sands

According to characteristic of the city underground engineering, Combining the instance of underground pass in the rich water sands in the one city, the way of ground dewatering has analyzed and dewatering result of deep well has qualitatively analyzed to subside to the earth''s surface, around building correctly subside at the same time. Observe results indicate that the way can be full of project needs. The paper has offered the construction example for the underground engineering in the rich water sand layer.
