预应力锚索计算在边坡防护中的应用

Application of Prestressed Anchorage Cable Calculation in Slope Protection

高等级公路边坡防护作为公路工程的一项重要施工内容,对公路工程质量和运营后的交通安全都有较大的影响.在易滑塌、稳定性差公路边坡防护中,预应力锚索防护是最常用的防护形式之一.对预应力锚索的计算,是设计与施工中的关键步骤.基于工程实践,对预应力锚索伸长量、压力表读数等常用数据进行计算和分析,分析了造成锚索预应力损失的影响因素,并提出了相应的防治措施.

Highway slope protection as an important content of highway construction project exerts great influence on highway engineering quality and traffic safety after the operation. For highway slope protection which is slump- prone and of poor stability,prestressed anchorage cable is one of the most commonly used forms of protection. Prestressed anchorage cable calculation is the key step of design and construction. Based on engineering practice,the paper calculates and analyzes common data such as prestressed anchorage cable elongation,analyzes the influential factors causing prestress loss of anchor cable,and puts forward several corresponding prevention measures.
