By calculation of water flow into tunnel and theoretical analysis for effect of blocking grouting circle combined with engineering analogy,the design principle and project of waterproofing and drainage system for Xiamen Subsea Tunnel were performed.

通过对隧道涌水量进行计算，对堵水注浆圈作用进行分析并结合工程类比后，分析确定了厦门海底隧道的防排水设计原则及方案，即在主隧道不良地质地段和整个服务隧道采用全封堵方案，水压按全水头计算；在主隧道完整围岩地段采用限量排放方案，水压可进行一定折减。

2The rock mass quality was assessed based on the data obtained from exploration adits with the methods of engineering geological classification for surrounding rock mass, BQ, RMR and Q-system successively. And then the correlations between the assessment results of different methods were discussed.

基于勘探平硐获取的资料，运用&围岩工程地质分类法&、BQ法、RMR法和Q系统法进行了地下厂区岩体质量评价；讨论了四种不同方法评价结果之间的相关性。

These results show high Mg, Ca, K, SO42- during lower runoff periods,because of purging effect of river water onto the bedrocks and caused major ions dissolution. When the water flow is greater than 38m3/s, these elements were diluted.

河水在低流量时(8m3/s)，河水对围岩有冲提效应，可将岩石中的Mg、Ca、K及SO42-带入河水中，而当水流量约大於38m3/s时，由於河水的稀释效应，使这些离子浓度随流量增大而降低。

And associated with aboundant solid bitumens.

根据红外光谱、色谱－质谱分析和反射率测定，揭示出含矿围岩不但是矿源层，而且是油源岩。

Wall-rock metasomatism, boilings and separation of fluid facies, as well as mixture with meteoric water were the main evolution processes in a fluid system. The activiti es of ore-bearing fractures can be divided into two states: brittle and brittle -ductile ones.

与围岩的交代作用，沸腾作用引起的相分离和大气降水的加入所产生的混合稀释是成矿流体体系演化的主要途径，容矿断裂构造活动可划分为脆性破裂和韧脆性扩张两种动力学状态。
