摘要
临海高等级公路灌河大桥主桥为双塔双索面半漂浮体系钢与混凝土组合梁斜拉桥,鉴于温度配切合龙的不确定性,该桥采用定时合龙方法。通过定时合龙施工技术、关键控制项点及质量措施的实施实践证明,该方法减少了温度配切合龙的种种制约,提高了合龙的可靠性及准时性,降低了施工风险。
Costal highway-Guanhe Bridge is a cable-stayed bridge combined with half floating system steel structure and concrete with double tower and double cable plane, according to the uncertain temperature＇s effect on the cutting method of closure, this bridge applied fixed-time closure. The practice had proved that this method could reduce the impact from the cutting method of closure, improved the reliability and reduce the construction risk through the fixed-time closure construction technology and implement of its key control points and quality measures.
