【摘要】 为了对云南省4条高速公路连拱遂道的健康状态评估提供依据及为以后修建连拱隧道在设计和施工上提供宝贵经验及教训,提高中国高速公路连拱隧道的施工和设计水平,尽可能减少衬砌开裂和渗漏水等隧道病害,采用现场调查方法对云南省玉元、元磨、大保和昆石4条高速公路连拱隧道衬砌开裂、渗漏水等病害进行了较为全面的调查,初步分析了隧道病害产生的主要原因并进行了相应的分类,并据此提出了连拱隧道设计和施工中其相应的病害预防和整治措施,以期为提高中国连拱隧道修建水平提供参考和借鉴。更多还原

【Abstract】 In order to provide the necessary data for evaluating the healthiness of arcade tunnel structures at the four highways in Yunnan province,accumulate lots of experiences and lessons for the arcade tunnel’s construction and design,improve the construction and design level of the arcade tunnels and reduce the defects of lining cracking and leakage as possible,defects of cracking and seepage in the arcade tunnel linings have fully been investigated at the four highways such as,Yuxi to Yuanjiang,Yuanjiang to Mohe,Dali to Baoshan and Kunming to Shilin in Yunnan province;the main causes inducing these defects are primarily studied and classified;some corresponding preventing and treating measurements,as well as some problems related to the arcade tunnel design and construction are put forward in order to provide some use for reference in construction of tunnel engineering.更多还原
