富水砂卵石地层土压平衡盾构水土压力计算分析

On calculation of balance shield's water-earth pressure in rich water pebble stratum

根据成都地区的地质条件和盾构施工特点,阐述了富水砂卵石地层盾构掘进的水土压力计算方法,并探讨了盾构掘进施工中水土压力的控制措施,有效降低了盾构施工风险。

According to the geological conditions and shield construction features of Chengdu,the paper illustrates the water-soil pressure calculation method of shield jack of rich water pebble stratum,and explores the controlling measures for the water-soil pressure in the shield jack construction,so as to lower the shield construction risks.
