土钉墙设计

土钉墙是一种原位土体加筋技术，是由设置于坡体中的加筋杆件与其周围土体牢固粘结形成的复合体以及面层构成。其作用类似于重力式挡土墙，用于深基坑支护与天然土坡的稳定。根据试验成果，结合工程实践监测，阐述土钉墙的工作原理，稳定性分析及有关设计参考的选定等。实践证明，土钉墙具有工作可靠、投资省及工期短等特点，具有很好的发展前景。

Soil nailing is a technique of insitu ground reinforcement that is bonded to surrounding ground to form combined unit. Its effect is similar to a gravity retaining wall. According to test results combined with engineering cases and monitoring, the principle of soil nailing wall, the calculation of its stability, the choice of its design parameter and installation are illustrated. The structure system may be used for supporting a temporary deep foundation pit and stabilizing a permanent slope. Monitoring of tlie soil nailing wall have showed that as a supporting system, the performence of the technique is reliable, economical and fastish. The author believes this technique will have a wide landscape of development in the future.
