高速公路边坡的稳定性关系到高速公路的行车安全与结构稳定性,而挡土墙是最常用的边坡支挡构造物之一。由于路堑的开挖破坏了边坡原有的平衡,受到自然因素、地质因素的影响,会使边坡出现变形滑动,破坏其稳定性,具有良好的经济效益。重力式挡土墙结构稳定,对边坡支挡效果好,可有效提高边坡的稳定性。文章基于重力式挡土墙施工实践,从重力式挡土墙的特点、施工技术要点和质量控制措施进行阐述,对施工一线具有一定的指导作用。
The stability of highway slopes is related to the traffic safety and structural stability of expressways. Retaining walls are one of the most commonly used slope supporting structures. As the cutting excavation undermines the original balance of the slope and is affected by natural and geological factors, it will cause the slope to deform and slide, destroying its stability and having good economic benefits. Gravity retaining wall structure is stable, supporting the effect of the slope, which can effectively improve the stability of the slope. Based on the practice of gravity retaining wall construction, this paper elaborates the characteristics of gravity retaining wall, construction techniques and quality control measures, which will guide the first line of construction.
