根据现场试验结果,研究了承受柔性荷载的带桩帽CFG桩复合地基中桩的承载特性、土的受力特性以及桩帽、桩和土之间相互作用规律。试验结果表明:极限状态下,带桩帽的CFG桩复合地基中桩承载力的发挥程度比地基土承载力的发挥程度略大;正常使用状态下,桩承载力的发挥程度远大于土承载力的发挥程度,桩的安全储备小于土的安全储备。 According to the field test results, the bearing behavior of the pile under CFG pile composite foundation subjected to flexible load, the force characteristics of the soil, and the interaction between the pile cap, pile and soil are studied. The experimental results show that under the ultimate state, the bearing capacity of pile with CFG pile foundation with pile cap plays a greater degree than the bearing capacity of foundation soil. Under normal conditions, the bearing capacity of pile is far greater than the bearing capacity of soil The safety deposit of pile is less than the safety reserve of soil.
