城市三维工程地质结构调查的数据采集、整理方法的探讨

Three-dimensional structure of urban engineering geological survey data collection and collation methods

工程地质勘察资料的采集、整理是城市三维工程地质调查的基础与基石。本文结合杭州城市三维工程地质调查工作,系统总结了资料采集在平面上按照网度、纵向按照亚层控制的方法和措施;通过建立建模孔、岩土层物理力学性质属性表,对工程地质层进行归一化处理;对未满足网度要求的盲点地区可以通过补充勘探工作量,完善建模孔系统,建立完善的工程地质采集系统。

Collection and collation of engineering geological survey data works the foundation and cornerstone of three-dimensional urban geological survey。In this paper,three-dimensional works in Hangzhou city geological survey work,summed up the data acquisition system in the plane,collected in accordance with the grid,vertical sub-layer control in accordance with the methods and measures; Hole through the establishment of modeling,physical and mechanical properties of rock and soil layers attribute table on the engineering geological layer normalized; Not meet the requirements of the blind spot of grid areas for exploration can be added workload and improve the modeling of pore systems,the establishment of a sound collection system engineering geology。
