复合土钉墙支护技术在某大型软土基坑围护中的应用

The Application of Composite Soil-nailing Technique for a Big Foundation Pit Support

摘要:

根据拟建建筑基坑的工程地质条件、周边环境条件、基坑开挖深度等特点综合考虑，对基坑分段采用超前微型桩支护加土钉墙、放坡加土钉墙2种复合支护方案。实践证明，该工程所采用的多种复合式支护实施方案，技术安全可靠，经济合理。

Abstract:

Based on the characteristics of the engineering geological condition, the peripheral environmental condition, and the foundation pit's depth, the foundation pit was dealt with the composite support plan of mini-pile support in advance with soil-nailing wall and slope with soil-nailing wall in partition. The composite support plans of the engineer are safe and economical. They can provide important reference to solving the problems of similar engineering design.
