桩基础负摩阻力的防治措施研究

桩基础在使用阶段由于受到负摩阻力的影响而产生的不均匀沉降对基础危害较大,因此要在设计及施工中考虑可能出现的负摩阻力以保证基础的稳定性,并采取必要的措施避免出现负摩阻力。系统分析负摩阻力产生的原因,并提出具体的防治措施。

Study on Preventive Measures for Negative Frictional Resistance of Pile Foundation

The non-uniform settlement of pile foundation caused by the negative frictional resistance will greatly destroy the foundation under its use. Therefore, it is necessary to consider the negative frictional resistance possibly causing in the design and construction so as to guarantee the foundation stability, and to take the essential measures to avoid the negative frictional resistance. The article systematically analyzes the cause of negative frictional resistance and proposes the detailed preventive measures.
