钢管土钉在唐山丰南沿海软弱土基坑中的应用

介绍了钢管土钉在沿海软弱土深基坑中的成功应用，阐述了在施工中采取的具体技术创新和处理措施。该工程使用钢管土钉创新，计算过程中采用与钢筋等面积代换，同时借鉴施工前钢管桩试验数据，对钢管土钉的结构进行改进，优化钢管土钉长度、间距以及钢管土钉与面层连接节点；通过严格的施工管理和技术追踪，加强施工中突发环节的准备，采用信息化施工，对施工中出现的薄弱环节作出相应的补强措施，工程在严格的质量和安全控制下，完成施工任务，保证了基坑安全以及工期要求。

Tangshan Steel Soil Nails in Soft Soil Foundation in the South Coast of the Application

Introduced the steel soil nails deep excavation in soft soil along the coast in the successful application, described in detail in the construction of technological innovation and to take concrete measures to deal with. The project will use innovative steel soll nails, and steel used in the calculation process of substitution of equal area, drawing on pre--eonstruetlon steel pipe pile test data, the structure of the steel soil nail to improve and optimize steel soil nail length, spacing, and steel nails and surface soil layer connection node; by strict construction of the project management and technical track, strengthen the con- struction of unexpected aspects of preparation, the use of information construction, the construction appeared to weaknesses in the corresponding reinforcement measures, and finally the quality of the works in strict and security control, complete the construction tasks to ensure the security pit, and schedule requirements.
