摘　　要：在桩基础的建设中,常出现实际混凝土用量大于理论混凝土用量的情况,充盈系数作为二者的比值,一定程度上能反映桩基础的建设情况。为明确桩基础灌注前的理论混凝土用量,推进精细化施工建设。本算法通过对桩基础建设中混凝土性质以及土层参数进行软件模拟计算,得到不同土层的变形情况,之后进一步对其他因素进行考虑,并使用桩孔三维检测数据进行修正,得到桩基建设中混凝土用量的参考值。最后通过与实际工程应用结果进行比较,表明该算法与实际工程混凝土用量基本吻合,可以为类似工程提供有价值的参考依据。In the construction of pile foundation, the actual concrete consumption is often greater than the theoretical concrete consumption. The filling coefficient, as the ratio of the two, can reflect the construction of pile foundation to a certain extent. In order to clarify the theoretical concrete consumption before pile foundation pouring and promote the refined construction. This algorithm obtains the deformation of different soil layers through the software simulation calculation of the concrete properties and soil parameters in the pile foundation construction, and then further considers other factors, and uses the three-dimensional detection data of pile holes to modify, so as to obtain the reference value of concrete consumption in the pile foundation construction. Finally, through the comparison with the actual engineering application results, it shows that the algorithm is basically consistent with the actual engineering concrete consumption, which can provide a valuable reference for similar projects.
