| Abstract: | Lime jet mixing piles were constructed to consolidate the soft foundation of the abutment of Nandiancun bridge, considering its lower weight bearing capacity because of the silt with more than 30% water content. The digging and dynamic testing results show that the requirement to the abutment that its bearing capacity should over 150kPa is satisfied. The method is characterized with simple equipment, convenient operation and good economic result.
