摘要
能量守恒定律是大自然的普遍规律,桩基础的沉降过程也必须满足这一规律。基于这一根本出发点,文中从能量转化的角度对单桩沉降过程进行分析,在此基础上建立一种新的单桩沉降计算方法。通过工程实例分析可知,土体参数的合理选择是计算精度得到保证的关键。利用符合实际情况的土体参数,通过能量方法计算的荷载位移曲线和桩侧摩阻力分布与实测数据基本吻合,验证了此方法的正确性。该方法力学概念清晰,对于理解桩基沉降过程具有重要意义。
The law of conservation of energy is a universal principle of nature,and thus the settlement process of pile foundations must comply with this law.Starting from this fundamental premise,this study analyzes the single pile settlement process from the perspective of energy transformation and establishes a new calculation method for single pile settlement.Engineering case analyses indicate that the reasonable selection of soil parameters is key to ensuring calculation accuracy.Using soil parameters consistent with actual conditions,the load-displacement curves and pile side friction distributions calculated by the energy method closely match measured data,validating the correctness of the method.This approach features clear mechanical concepts and holds significant value for understanding the pile foundation settlement process.
