摘要： This paper serves to appraise the monetary cost of coastal recreational resources in Qingdao using the travel cost method (TCM), which is typically used in developed countries. The total revenue produced by Qingdao’s coastal recreational resources is about RMB 5.51×10 annually, based on questionnaires given at Qingdao’s major tourist destinations. These questionnaires establish correlation functions that factor in the number of tourists, travel expenses, etc. The data processing software named Eviews was used to determine the tourist demand regression curve and to calculate their residual and actual travel expenses. The results of this study can provide a scientific basis for applicable industries interested in development and management decision-making. Therefore, this study assesses the reasonable usage of coastal recreational resources.

马栋,谭忠盛

《中国工程科学》 2009年第11卷第7期页码 45-52

摘要：

青岛胶州湾隧道工程全长7 800 m，下穿海域3 950 m。有两条主隧道和一条服务隧道，在青岛端距离洞口2 000 m处设有进出海底隧道的匝道。主隧道海域段线间距约55 m，断面为椭圆形断面，隧道断面宽16 m，高12 m，隧道洞身主要位于微风化花岗岩、辉绿岩、安山岩中，纵断面采用“V”字坡，最大海水深42 m，隧道最小埋深不小于30 m。对钻爆法修建青岛胶州湾海底隧道的关键技术和大型施工机械配套进行了探讨。
