某高墩大跨连续刚构在悬臂施工过程中,在已施工的箱梁(最多为3个节段)腹板锚下顺着波纹管方向产生了斜裂缝。通过分析研究,锚下混凝土主拉应力过大是产生裂缝的重要因素。根据研究结论,提出了有效的解决措施,取得了较好的处理效果。
Long-span continuous rigid frame of a high pier In cantilever construction, diagonal cracks are produced along the corrugated pipe under the anchors of the box girders (up to 3 segments) that have been constructed. Through analysis and research, the main stress of anchor under anchor is an important factor of cracks. According to the conclusion of the study, effective solutions are put forward and a better treatment effect is achieved.
