At the same time, liquid coal ash is used in backfilling of abutment, so as to reduce the load and basic stress, reduce settlement and increase the dense of fillings.
同时，为降低桥头地基的荷载和基础应力，减少沉降并增加填料的密实度，台背回填采用液态粉煤灰填筑。
3
Pile's capacity is computed, and two modes are adopted to compute pile's additional stress and settlement, the pressure of hitting pile is analyzed.
