【摘要】：面对工业建筑深基坑施工时复杂性的施工环境,对原有建筑的防护支护将是施工前需要重点考虑的内容。常用的施工方法有:地下连续墙、钢板桩、土钉墙、桩锚等,由于多种环境及客观条件的存在,任何一种方法就能独立完成的,而是更多的采用复合施工的支护形式,以满足设计及规范要求,并能在工期、安全、经济上做到最大优化。论文以唐山某钢铁厂矿焦槽基坑工程为研究对象,以研究复合土钉墙支护形式在复杂条件下工程建筑深基坑中的应用为目的,通过理论研究与应用实例相结合的方法,重点对复合土钉墙整体稳定性、设计情况、设计参数等内容进行了剖析,从理论上分析了结构良好的受力特性,并以实例工程的具体分析了基坑支护方案计算、施工组织以及基坑监测方案。证明了复合土钉墙支护结构的可操作性,文章经过从理论到实践的分析得到了以下结果:复合土钉墙支护结构在钢铁、冶金等重工业工厂的基坑施工中,可操作性强、经济效益显著,应用非常成功。
[Abstract]:In the face of the complex construction environment of deep foundation pit construction of industrial buildings, the protection and support of the original building will be the important consideration before construction. The commonly used construction methods are: underground continuous wall, steel sheet pile, soil nailing wall, pile anchor and so on. Because of the existence of many kinds of environment and objective conditions, any one method can be completed independently, but more adopt the support form of compound construction, to meet the design and specification requirements, and can be in time limit, safe, In order to achieve the maximum economic optimization, the paper takes the foundation pit engineering of a iron and steel mine mine in Tangshan as the research object, and studies the application of composite soil nailing wall supporting form in the deep foundation pit of engineering buildings under complex conditions. Based on the method of combining theoretical research with practical examples, the overall stability, design situation and design parameters of composite soil nailing wall are analyzed, and the good mechanical properties of the structure are analyzed theoretically. The calculation of foundation pit support scheme, construction organization and foundation pit monitoring scheme are analyzed with examples. The feasibility of composite soil nailing wall supporting structure is proved. Through the analysis from theory to practice, this paper obtains the following results: the composite soil nailing wall supporting structure has been applied successfully in the foundation pit construction of heavy industry factories such as iron and steel, metallurgy and so on, which has the advantages of strong maneuverability, remarkable economic benefit and successful application.
