海南中部特殊气候桥梁施工控制要点

Key Construction Points of Bridges in the Central Area of Hainan Province During Special Climates

海南省琼中至乐东高速公路(琼中至五指山段)工程A4合同段位于海南中部。以该工程毛阳特大桥桩基及下部结构施工为例,针对工期紧迫、地处陡峭山腰地段、暴雨山洪多、便道修建困难的桥梁施工进行研究。提出了具体实际可行性的山区高速公路施工进度控制措施与管理办法,并付以实施。

The A4 contract section of the Qiongzhong-Ledong Expressway(Qiongzhong to Wuzhishan Section)in Hainan Province is located in the central part of Hainan Province.Taking the pile foundation and substructure construction of Maoyang Bridge as an example,the bridge construction was studied under the conditions of tight construction period,steep mountainside,heavy rain and mountain flood,and difficult construction of the access road.The control measures and management measures for the construction progress of the mountain highways with specific practical feasibility were proposed and implemented.
