摘要
盾构设备的选型对地铁区间盾构施工有很重要意义,盾构选型的合适性直接影响到盾构施工的安全性。针对淮安东站地铁隧道所遇到的富水砂层地质条件,通过比较地质特征、颗粒级配、渗透系数、周围环境、经济因素,分析了淮安东站地铁隧道土压平衡盾构机和泥水平衡盾构机的优缺点。从而提出了适用于本工程施工用的盾构机型。
The selection of shield equipment is of great significance to the construction of shield tunnels in the subway.The suitability of shield selection directly affects the safety of shield construction.According to the geological conditions of the water-rich sand layer encountered in the Huai′an East Railway Tunnel,the earth pressure balance shield machine of the Huai′an East Railway Tunnel is compared and analyzed through geological characteristics,particle gradation,permeability coefficient,surrounding environment and economic factors.The advantages and disadvantages of the mud-water balance shield machine are done.Therefore,a shield type suitable for the construction of this project is proposed.
