摘要
斜腿刚构具有造型美观、受力合理、使用材料经济等优点。但是由于其结构受力特性与拱桥有相似之处,同样会对基础产生较大水平推力,因此本桥型多用于地基条件较好的地区。结合桂林市临桂新区新龙路桥的设计,论述斜腿刚构在岩溶发育、土层分布不均的复杂地质条件下的设计和计算方法。
Slant leg rigid frame is a structural system with beautiful appearance, rational strength and ideal economic indicators. However, since slant leg rigid frame has the characteristics of producing great thrust to the ground similar to arch bridge, this type of bridge is often built in places with good foundation. Combined with the design of Xinlong Road Bridge in Lingui New District of Guilin City, the design and calculation methods of slant leg rigid frame under complex geological conditions of karst development and uneven soil distribution are illustrated in this article.
