摘要
针对岩溶区域桥梁工程地质勘测中传统二维钻孔图难以直观展示溶洞三维空间分布的问题,提出基于建筑信息模型(building information modeling,BIM)技术的溶洞三维建模方法,以辅助桩基施工方案设计。以某高速铁路连续梁桥岩溶桩基为研究对象,利用Revit软件的族常规建模方式,结合地质钻孔数据,建立溶洞三维模型。通过溶洞连通性假设优化模型,并采用Lumion软件实现三维漫游,直观展示溶洞形态及空间分布。模型成功揭示了研究区域内2个主要溶洞的空间特征,其中,1号溶洞体积37 m^(3)、2号溶洞体积232 m^(3),分析了溶洞与桩基的位置关系及填充情况,并据此提出了针对不同桩位的钢护筒分层施工方案。
Given the difficulty that two-dimensional borehole maps cannot visually reveal the three-dimensional spatial distribution of Karst caves in bridge geological surveys conducted in Karst areas,a three-dimensional Karst cave model based on Building Information Modeling(BIM)technology is proposed to assist pile foundation construction design.The Karst pile foundation of a high-speed railway continuous-beam bridge is taken as the research object,and a threedimensional cave model is built using the Revit family routine method combined with geological drilling data.The cave connectivity hypothesis is optimized,and three-dimensional roaming is achieved through Lumion software to intuitively display cave morphology and spatial distribution.The spatial characteristics of the two main Karst caves in the study area are successfully revealed:Cave No.1 has a volume of 37 m3,and Cave No.2 has a volume of 232 m3.The relative position and filling condition between each cave and the pile foundation are analyzed.Consequently,a layered steel casing construction scheme is proposed for different pile positions.
