摘要
阐述了钻孔后注浆连续墙和喷锚组成的复合支护新技术,应用结果表明,本新型基坑支护方法解决了三个难题:①复杂地质条件下如何保证基坑工程既安全又经济;②基坑外挤土桩对支护结构引起的附加水平应力的影响;③施工过程中基坑意外超挖引起的基坑安全性。
The result of the application of such a new shows, three difficult problens were solved by such a new method. They are ：1. how to guarantee the softy and saving of the construction; 2. how to take care the effect of horizontal stress to the bracing structure ; 3. how to keep the safety of foundation pit in case overexcavation outside of the pit during consruction.
