From the angle of engineering application, this article analysed the corrosion characteristics and damage causes of the current structural used concrete in the region of Hangzhou gulf, on the basis of on-site survey of all the Marine concrete projects in that area. Taking HPC used in Marine as research objective, this article put great emphasis on the influence of the composition cementing material system to concrete performance, and make a preliminary probe into the action mechanism of the composite effects of various mineral materials in improving the performance of concrete by laser measuring size machine and EMPA. Through experiments, the article discussed how chloride ingression in concrete will be effected by such factors as exposure time, chloride binding, environment temperature, stress and cracks conditions; and also analysed the symptoms of these factors in the model of concrete service life prediction by conference to all related research reports both home and aboard. On the foundation of abovementioned research, this paper brought up an engineering model of service life prediction of marine concrete, which is based on chloride-induced corrosion.

本文从工程应用的角度，在对杭州湾地区既有海工混凝土工程作实地调研的基础上，研究分析杭州湾地区既有海工混凝土结构的腐蚀特点和破坏原因；以海工高性能混凝土为研究对象，着重研究复合胶凝材料体系对混凝土性能的影响，并应用激光粒度仪、EMPA等分析手段，就复合胶凝材料的作用机理进行初步探讨；试验研究混凝土暴露时间、胶凝材料对氯离子的吸附、环境温度、应力和裂缝状态等因素对混凝土中氯离子迁移运动的影响，并结合国内外相关研究报导，探讨这些因素在混凝土使用寿命预测模型中的表征；在上述研究基础上，提出以氯离子侵蚀为基础的海工混凝土使用寿命预测的工程应用模型。

In company with nonstop rushing of the long-span tunnel construction, a matterstation encounter more and more. For instance, the demand of the present design and construction code is already insatiability with the need of long-span tunnel engineering design and construction. And both domestic and foreign concerned research output is not too much to refer. So the engineering design and construction on long-span tunnel has definite blindness of the approve use for reference.

随着大跨度隧道建设的不断涌现，所遇到的问题也越来越多，比如现行的设计与施工规范已经不能满足大跨度隧道设计与施工的需要了，但国内外有关的研究成果并不多，可借鉴的设计与施工经验较少，大跨度隧道的设计与施工带有一定的盲目性。

Nowadays, with the rapid development of cities and industries, human activities take on the characteristics of expansibility and instantaneousness, which produce much information data correspondently. The former information treatment methods in the field of soil, engineering can"t meet the users" demand on exactness and alternation. So the visual evaluation of liquefaction information system becomes the urgent task in soil engineering.

当今，随着城市化和工业化的加快，人类活动呈现出空间扩展性和时间瞬时性的特点，相应产生了大量的信息数据，原有的岩土工程信息处理方法已不能完全满足用户对信息的准确、直观、迅速、可交互等多样性需求，因此地震砂土液化的可视化评价信息系统是岩土工程界迫切需要解决的课题。
