| 摘 要： | 轻骨料混凝土与普通混凝土在材料性能上存在一定的差异,导致其用于连续刚构桥时,在设计方法和施工工艺等方面都与普通混凝土有所区别。以水土嘉陵江大桥为例,依据《轻骨料混凝土桥梁技术规程》,对两种混凝土在局部受压性能上存在的差异进行了分析。分析结果表明,轻骨料混凝土局部承压性能低于普通混凝土,而且当与普通混凝土采用相同设计参数时,其局部承载力验算结果无法满足规范的要求。采用掺入适量钢纤维的措施,可以有效的改善轻骨料混凝土局部承压性能,使其局部受压承载力达到规范的要求。

| Abstract: | The crafts of the design and construction of long span continuous frame bridge using lightweight aggregate concrete are different from those using common concrete,since the performance of lightweight aggregate concrete is different from that of the common one.Taking the Shuitu Jialingjiang Bridge as an example,the differences of the performance of local compression between lightweight aggregate concrete and that of common concrete are analyzed according to the standard of "Technical Specification for Lightw... |
