针对北京站至北京西站地下直径线工程泥水盾构施工，通过对泥浆性能研制的配比试验，提出了砂卵石条件下的最佳泥浆配比，提高并改善了泥浆的成形质量与速度，确保了环境要求。对类似工程有一定的借鉴作用。

Aiming to the slurry shield construction of underground diameter project from Beijing railway station to Beijing railway west station, the optimum slurry ratio in the condition of sandy gravel was proposed through the proportional tests, which improved the forming quality and velocity of the slurry and ensuring the environmental requirements. It can supply some experience to the similar projects.
