Abstract:

For the high filling slope with soft soil foundation, it is an essential problem to consolidate the soft foundation to ensure slope safety. As a kind of gravity retaining wall, the cement mixing pile is a reliable foundation treatment technology to prevent the slope from collapse. Aiming at a slope engineering of a domestic nuclear power plant, we figured out a design solution of gravity retaining wall of cement mixing pile, verified the stability and optimized the insert depth and replacement rate in terms of saving working amount and lowering cost.

Key words: filling slope, soft foundation, cement mixing pile, optimization
