顶管在流砂土层中的施工技术

Engineering Techniques of Pipe Jacking under Quick Sand Condition

随着我国经济的发展和人们环保意识的增强，顶管作为一种非开挖施工方法得到了广泛应用，在城市建设中应用的领域也越来越宽。但复杂多变的地质条件也给顶管施工带来了一定的风险，本文以广州市某污水工程顶管施工为例，介绍了在流砂地质条件下，顶管施工所要注意的事项和应对措施，以供工程技术人员和同类工程参考。

With the rapid development of China＇s economy and the rise of public awareness on environmental protection, the construction of pipe jacking have become a common construction method and it has been widely used in the municipal construction. The uncertainty of the underground engineering, especially under the complex geology condition, pipe jacking construction is faced with risk. Base on the pipe jacking of sewage engineering in Guangzhou, some scientific suggestions have been put forward for pipe jacking under quick sand condition, engineers and similar projects can reference to the result.
