摘　　要：地下管廊、电缆隧道砼结构产生裂缝的原因很多,但人们一直忽略了钢筋保护层厚度的增加和减少对混凝土结构产生裂缝的影响。在施工过程中,我们找到了导致钢筋保护层产生误差的原因和通过施工措施解决了钢筋保护层厚度的施工误差,减少了管廊、电缆隧道砼结构裂缝的产生。There are lots of cracks causes of underground pipe gallery, cable tunnel concrete structure, but people have ignored the influence of the reinforced protective layer thickness increases and reduce on cracks in the concrete structure, In the construction process, we find the cause of reinforced protective layer to produce error, and reinforced protection layer through the construction measures to solve the thickness error of rein- forced protective layer construction, reducing the production of pipe gallery, cable tunnel concrete structure cracks.

关 键 词：地下管廊 混泥土裂缝 保护层 厚度偏差 纠正措施
