应用BIM技术辅助判定工程桩入岩深度

Auxiliary Determination of Engineering Pile Depth into Rock by Application of BIM Technology

针对常规判定工程桩入岩深度方法存在的主观性强、误差较大等问题,在充分的理论研究基础上,结合宁波国际会议中心项目实践,提出基于BIM技术辅助判定工程桩入岩深度的方法。通过BIM技术建立工程桩三维模型和硬质基岩面模型,并进行整合分析,获取每根工程桩入岩后的桩底高程,生成桩底高程图纸,指导现场桩基施工。该方法不仅提高工程桩入岩深度判定精度,且在施工前获取高精度桩深数据,对桩基施工前期准备和现场施工具有重要意义。

Aiming at the problems of strong subjec tivity and large error in the conventional method of determining the depth of engineering pile into rock,based on sufficient theoretical research and combined with the project practice of Ningbo International Conference Center,a method of auxiliary determination of engineering pile depth into rock based on BIM technology is proposed.The 3D model of engineering pile and hard bedrock surface model are established through BIM technology,and integrated analysis is carried out to obtain the pile bottom elevation of each engineering pile after entering the rock,generate the pile bottom elevation drawing,and guide the onsite pile foundation construction.This method not only improves the judgment accuracy of engineering pile depth into rock,but also obtains high-precision pile depth data before construction,which is of great significance to the preliminary preparation and onsite construction of pile foundation construction.
