一种组合式衡重挡土墙设计方法

A Design Approach of Composite Balance Weight Retaining Wall

衡重式挡土墙在道路工程建设中占有较大比例,但墙高时,存在截面大、圬工量大、施工进度慢等缺陷,因此对其进行优化设计具有重要的工程意义。针对上述问题,提出了一种钢筋混凝土与砌体组合的衡重式挡土墙设计方法,给出了相应的计算模型及构造措施,通过理正岩土的挡土墙设计计算论证了方案的可行性。并结合边坡治理工程实例,进行了方案对比,结果表明本设计方法在经济性和环境效益等方面取得了良好的效果。因此组合式衡重挡土墙设计方法在岩土工程中有广阔的市场前景,也为类似工程提供了借鉴意义。

Balance weight retaining wall occupies a large proportion in road construction, but as the wall is high, it will have some imperfections, just as a large section of masonry area, a large quantity of masonry and slowing down the construction-progression, so it has important engineering significance to optimize its design. In order to solve the above problems, this paper proposes a method of reinforced con- crete-and-masonry retaining wall, gives the calculation model and the construction measures, using the retaining wall design of Lizheng soil calculation to demonstrate the feasibility of our program. Combined with the real slope engineering examples, it＇s indicate that the new design has achieved good results in economic and environmental benefits. So the combination of balance weight retaining wall design method will have abroad market prospect in geotechnical engineering and provide solving ways for the similar engineering as well.
