软岩边坡加固中锚索预应力变化影响因素分析

预应力锚索被广泛应用于边坡加固,并获得了良好的加固效果和经济效益,但针对锚索预应力的影响因素及变化规律的研究还不多见。本文简要分析了预应力锚索的受力形式,结合实际软岩边坡工程,比较分析施工期和雨季中大量的监测数据,详细探讨了边坡在最不利时期中影响预应力变化的主要因素及变化特点。主要包括锚索材料、施工影响及外部因素等,对进一步综合归纳预应力变化的规律及计算模型的确定有一定的参考价值。

Analysis of Influencing Factors of Prestressing Force in Reinforcing Soft Rock Slopes

Prestressing force is applied in reinforcing slope engineering,and has gotten good strengthening effect and economic benefit.But there is few research about influencing factors and theoretical study.Firstly,the mode of action of prestressing cables is described.Combined with a practical soft rock slope and based on the monitoring data during the construction phase and rainy days,the main influencing factors and variation features of prestressing force in the worst phases are analyzed in detail,which includes the influence because of material factor,construction factor and external factor.It can be reference to setting up the theory and calculation model of prestressing force.
