中深基坑膨胀土支护施工技术应用研究

The application research on mid-deep foundation pit expansive soil support construction technology

结合工程实例,分析了中深基坑膨胀土支护施工的重难点,从土方开挖、护坡施工、土钉及锚杆施工、支护桩施工等方面,阐述了基坑支护的总体思路与技术方案,通过实践表明,该基坑支护方案实现了经济社会效益的最大化。

Combining with the engineering example,this paper analyzed the key and difficult points of mid-deep foundation pit expansive soil support construction,from the earth excavation,slope protection construction,soil nail and anchor rod construction,support pile construction and other aspects,elaborated the general idea and technology scheme of foundation pit support,through the practice showed that the foundation pit support scheme realized the maximization of economic and social benefits.
