联合勘察技术在某大型试验厂房中的应用

Application of joint investigation technology in a large test building

某大型试验厂房建筑结构具有竖向荷载大、水平振动荷载大的特点,而因其特殊性需要,对建筑及地基基础变形要求极其严苛。常规单一的勘察与土工测试方法无法实现勘察目的,不能满足本项目建筑设计要求以及项目运营后对试验精度的要求。因此,本次勘察过程中采用了钻探、主动源面波法、电磁法、特殊性岩土试验及桩基动力特性测试等多种技术手段,获得了较好的勘察效果。本文简单介绍了该项目基本情况及上述各种测试方法的流程及数据成果,通过对各种测试成果的相互验证及相互补充,说明了联合勘察技术在本项目中应用的有效性和必要性。

The large test building faces the large vertical load and horizontal vibration load,and the requirement of the building foundation deformation is very strict due to its special needs.The conventional single survey and geotechnical test methods cannot meet the requirements of the project design and the accuracy requirements of subsequent project operation.So various technical methods such as drilling,active source surface wave method,electromagnetic method,special rock tests and the dynamic property tests of the pile foundation are adopted in this survey,and good results are obtained.The basic situation of the project and the data results of these various test methods are introduced in this paper.The verification and mutual complement of various test results show the effectiveness and necessity of joint survey technology in this project.
