针对富水地层地下连续墙成槽施工泥浆重度设计计算方法问题,建立槽壁整体稳定性极限平衡分析力学模型,推导得到保证地下连续墙槽壁整体稳定的成槽施工泥浆最小重度计算公式,并进行实例验证和分析。研究结果表明:所建立的基于槽壁整体稳定的地下连续墙成槽施工泥浆重度设计计算方法是可靠的,同时,为确保成槽质量,实际工程应用过程中,泥浆重度理论计算结果的安全系数取1.3~1.5较为合适。
Aiming at the problem of the severe design and calculation method of the slurry in the construction of underground continuous wall in the water-rich stratum, the mechanics model of the limit equilibrium analysis of the integral stability of the trough wall is established and the minimum and severe calculation formula of the trenching construction slurry is derived. Example verification and analysis. The results show that the established calculation method for the design and construction of the underground continuous wall based on the integral stability of the slot wall is reliable. Meanwhile, in order to ensure the quality of the slotted slot, the safety factor Take 1.3 ~ 1.5 is more appropriate.
