重力式地锚在沙漠地区架空输电线路施工中的应用

Application of Gravity Anchor in Construction of Overhead Transmission Lines in Desert Area

利用重力式地锚可从根本上克服沙漠土质易坍塌的缺点,并可以减少地锚开挖对土壤的扰动。文章介绍了重力式地锚的技术原理、受力分析及配重物计算,并通过试验验证方案的可行性,对重力式地锚在沙漠地区架空输电线路施工中的应用提出建议。

The use of gravity anchor can fundamentally overcome the shortage of desert soil which is easily to collapse,and can reduce the disturbance of soil during anchor excavation.This paper introduces the technical principle,the force analysis and the counterweight calculation of the gravity type ground anchor,and proves the feasibility of the scheme through the experiment.Then puts forward some constructive suggestions on the application of gravity anchor in the construction of overhead transmission lines in desert area.
