摘要
为了研究预应力锚杆在设计阶段的关键设计参数,以龙岩某美食城抗浮设计项目为案例进行研究和分析.在介绍了几种抗浮方法和应用案例的基础上,对预应力锚杆抗浮设计的方案进行设计.结合相关的规范要求,对预应力锚杆荷载特征值、锚固体长度、锚杆筋体截面面积和注浆体承压面积等进行公式验算,根据验算结果进行梳理锚杆的构造特点和施工工艺.研究表明,通过不同参数影响分析,本项目抗浮锚杆设计符合规范规定的要求,满足锚杆甲级抗浮的要求.
Abstract
In order to study the key design parameters of prestressed anchor rods during the design phase,a case study and analysis were conducted on the anti floating design project of a food city in Longyan.Based on the introduction of several anti floating methods and appli-cation cases,a design scheme for the anti floating of prestressed anchor rods is proposed.Based on relevant regulatory requirements,formula verification is carried out on the load characteristic values of prestressed anchor rods,anchor body length,cross-sectional area of anchor rod reinforcement,and pressure bearing area of grouting body.Based on the verification results,the structural characteristics and construc-tion technology of anchor rods are sorted out.Research has shown that through analysis of the influence of different parameters,the design of the anti floating anchor rod in this project meets the requirements of the specifications and satisfies the Class A anti floating requirements of the anchor rod.
