BIM在上海地区岩土工程勘察中的应用

近年来,建筑信息模型(Building Information Modeling,以下简称“BIM”)技术逐渐成为建筑三维建模和可视化主要的信息技术,如何将其应用到勘察工程,实现勘察成果可视化,是当前岩土工程研究的热点。为了将BIM技术应用到实际勘察工程,结合上海地区岩土工程勘察实例,利用克里金插值法对采集数据进行插值拟合,然后将插值数据和原始数据进行整合。同时,对Revit子程序进行二次开发,基于Dynamo编写了一段生成三维地质体模型的程序,将整合后的数据导入程序,可生成符合真实地层情况的三维地质模型。该模型还将土层的非几何信息与模型挂接,为成果使用人员提供了土层走向和直观的土层物理力学性质展示。

Application of BIM in Geotechnical Investigation in Shanghai Area

In recent years,BIM Technology has gradually become the main information technology for building 3D modeling and visualization.How to apply BIM technology to survey engineering and realize the visualization of survey results is the hot spot of geotechnical engineering research.Based on the purpose of applying BIM technology to the current investigation project,this paper combines the case of Shanghai geotechnical engineering investigation,uses Kriging interpolation method to interpolate and fit the collected data,and then integrates the interpolation data with the original data.At the same time,the second development of Revit subroutine is carried out in this paper.Based on Dynamo software,a program for generating 3D geological body model is compiled.By importing the integrated data into the program,a three-dimensional geological model can be generated.Meanwhile,in the model,the non-geometric information of soil layer is directly linked with the model,which provides the users with soil layer trend and intuitive physical and mechanical properties of soil layer.
