钻孔灌注桩在进行单桩竖向抗压静载荷检测时,桩顶沉降量随着桩顶竖向荷载的增大而增大。桩顶沉降量包括桩身压缩量和桩的沉降量。本文利用有限元数学计算模型,算出了不同桩径、不同桩型在桩顶荷载作用下的桩身沉降量,并结合工程实例,通过对理论计算数据和实际检测数据的对比分析,得出了桩身压缩量占桩顶沉降量的比例。
When the bored pile is used to test the vertical static pressure and static load of a single pile, the settlement of the pile top increases with the vertical load of the pile top. Pile top settlement includes the amount of pile compression and pile settlement. In this paper, the finite element mathematical model was used to calculate the pile diameter of pile with different pile diameters and different types of pile under the load of pile top. Based on the engineering examples and the comparison between the theoretical calculation data and the actual test data, Proportion of the pile body to the top of the pile settlement.
