桥梁是公路工程中跨越河流、峡谷、公路、铁路等的重要构造物,桥梁混凝土梁(板)是桥梁中的直接承重结构,其质量关系到整座桥梁的寿命和行车的安全。桥梁混凝土梁(板)产生施工裂缝的原因主要有施工原材料、施工配合比、施工工艺、施工温度、养护条件、施工外部荷载。针对产生的原因采取有效的预防措施。
Bridges are important structures in highway engineering that span rivers, valleys, roads, railways, etc. The concrete beams (slabs) of bridges are direct load-bearing structures in bridges. The quality of bridges is related to the life span of the entire bridge and the safety of driving. The main causes of construction cracks in bridge concrete beams (slabs) are construction materials, construction mix, construction technology, construction temperature, curing conditions and construction external loads. Take effective precautions against the causes.
