Conformation Design and Statistical Analysis of Large Underwater Shield Tunnel
摘要
Abstract
Based on conformation design of large underwater shield tunnel at home, combined with typical engineering practice of shield construction abroad, this paper analyzes current conformation design of underwater shield tunnel in our country;statistically analyzes the correlation between segment external diameter and constitution design parameters of lining concerning segment wedge, lining thickness, segment partition number, central angle of standard piece and standard weight;discusses the relationship between segment thickness and maximum water pressure, between diameter of tunnel external segment and minimum thickness of covering layer. The research results show that the joint structure of large underwater shield tunnel in China tends to employ single sealing, smooth joint without rabbet, and universal wedge-shaped segment of plate type and staggered assembling;the external diameter of segment ring positively correlates to segment thickness, number of blocks and standard weight of segment.关键词
