【摘要】：本论文以广州-深圳-香港客运专线中的福田高铁客运站的施工为出发点,结合其复合地层大型超深特点,通过分析近接超高层建筑群超深基坑的环境保护和安全控制需求,对背景工程采用的新工艺进行了研究,掌握了一些新型的复合地层中处于超深超厚状态下的连续墙的施工方法;结合硬岩地层地下连续墙嵌岩深、墙体超厚的特点,形成了成槽技术的地层匹配性分析与评价技术。本文的预期创新点是基于福田高铁站的地下连续墙超深超厚得出的,其具体有下:(1)本文仔细分析了福田高铁站中的地下连续墙的施工全过程,结合施工手册,点名了施工过程中的关键工序以及质量的控制要点,并基于此得出了一套适用于大中型超深超厚地下连续墙施工的技术体系。(2)针对嵌入基岩硬度不同,提出了基于硬度的基岩等级划分与成槽技术地层适应性分析评价方法,这种方法对于超深超厚的连续墙施工中的成槽技术有着很大的借鉴意义。
[Abstract]:Based on the construction of Futian High Speed Railway passenger Station in Guangzhou-Shenzhen-Hong Kong passenger dedicated Line, combined with the characteristics of large and ultra-deep composite strata, this paper analyzes the environmental protection and safety control requirements of ultra-deep foundation pit in the near super high-rise building group. The new technology used in background engineering is studied, and some new construction methods of continuous wall in ultra-deep and super-thick state in composite stratum are mastered, and combined with the characteristics of embedded rock depth and super-thick wall of underground continuous wall in hard rock formation, The formation matching analysis and evaluation technology of grooving technology is formed. The expected innovation of this paper is based on the ultra-deep and super-thick underground continuous wall of Futian high-speed railway station. In this paper, the whole construction process of underground continuous wall in Futian High Speed Railway Station is carefully analyzed. Combined with the construction manual, the key working procedures and the key points of quality control in the construction process are listed. Based on this, a set of technical system for the construction of large and medium super deep and super thick underground continuous wall is obtained. Aiming at the different hardness of embedded bedrock, the method of classification of bedrock grade based on hardness and analysis and evaluation of formation adaptability of grooving technology is put forward. This method can be used for reference in the construction of super-deep and super-thick continuous wall.
