滑动测微计在黄土地区超高层建筑桩基中的应用
摘要:近年来，国家正在进行“一带一路”建设，超高层建筑在西北各地大量涌现。在超高层建设过程中，桩身内力状况越来越受到设计人员的重视。相比于传统的桩身内力测试方法，滑动测微计技术具有明显的优势。结合实际工程案例，重点介绍滑动测微计技术在黄土地区超高层桩基施工中的应用效果，以加深对黄土工程特性的认识，获得黄土地区后注浆灌注桩施工工艺、承载力性状及分布特点等方面的关键数据，为今后西北黄土地区超高层建筑提供必要的施工经验及技术指导。
Abstract:A large number of super high-rise buildings have been built in northwest China in recent years because of the developing of the “One Belt and One Road”.During the construction of such buildings,engineers are paying more and more attention on the internal force condition of pile.In comparison with the traditional test method for pile internal force,the technique of sliding micrometer has obvious advantages.Based on a case study in which the application effectiveness of the sliding micrometer technology was evaluated in the construction of pile foundation for super high-rise buildings,this paper provide key data on post-grouting pile construction technology,bearing capacity and its distribution characteristics so as to deepen the understanding of loess engineering characteristics and provide guideline and reference for similar projects in future.
