岩土综合勘察技术在风力发电场地基工程中的应用

Application of Geotechnical Integral Exploration Technology in Wind Power Generation Site Foundation Engineering

以风力发电场工程勘察为例,介绍了岩土综合勘查技术在不同的地形地貌、地层和水文地质条件中的应用。由于拟建工程的风机塔基大多数坐落于地势较高的山坡处,故采取以井探、槽探方法为主,工程物探为辅的勘察方法;对于位于平缓地带的办公区、生活区和变电站的场地勘察,则运用了土层剪切波速测试和静力触探试验的方法。通过各种岩土勘察技术的应用,掌握了该场地的地基土层物理力学性质指标及地基适宜性。地基变形监测和建筑物的稳定性检测结果显示,应用该方法所提供的岩土设计参数和各种施工方案经济合理、目的性和针对性强。

To take the wind power generation site engineering exploration as example, introduced the application of geotechnical integral exploration technology in different topographic reliefs, strata and hydrogeological conditions. Since the wind mill tower foundations of proposed engineering are mostly located on the topographically high slopes; so shaft test and trenching are mostly used, supplemented with engineering geophysics. As for site exploration for office area, living quarter and transformer substation those located on the flattish terrain, solum shear wave test and static sounding are used. Through the application of varied geotechnical exploration technologies, have identified foundation sola physical and mechanical property indices and groundwork adaptabilities. Groundwork deformation monitoring and structure stability detecting results demonstrated that the method provided geotechnical design parameters and various construction schemes are economic and reasonable with performance oriented to the point.
