摘　　要：土钉墙支护结构作为一种较好的原位土加固技术,具有施工速度快,安全经济等优点,被普遍应用在基坑工程支护结构中。本文针对基坑支护结构的机理,通过对某沿海城市基坑工程土钉墙支护结构的水平位移及土体深层水平位移进行监测,对基坑施工技术、监测方案以及监测数据进行了详尽分析,结果表明基坑工程中土钉墙支护技术的信息化监测应用具有较好的经济性和适用性,对今后类似工程提供有价值的工程经验。The soil nailing wall is widely used in the supporting structure of foundation pit engineering as a better in-situ soil reinforcement technology, due to the advantages of soil nailing wall, such as the fast construction, safety and economy, and so on. In this paper, by the working mechanism of supporting structures of foundation pits, the monitoring and analysis of horizontal displacements of soilnailing walls and deep soils in a foundation pit of a coastal city were carried out. Moreover, the monitoring program and monitoring data of foundation pits were analyzed in detail, as well as the construction technology. The results shown that the application of the information monitoring to soil-nailing walls in foundation pits has economy and applicability, and this provides valuable engineering experiences for similar projects in the future.
