围岩

The oar was noted to reduce rate of meet an emergency of shallow ministry country rock above all after bracket wall, restrained country rock inside bigger range be out of shape, what controlled tunnel thereby is intense be out of shape.

支架壁后注浆首先减小了浅部围岩应变率，抑制了围岩在更大范围内的变形，从而控制了巷道的强烈变形。

The results show that the ranges of secondary stress distribution have differences corresponding to different wall rock conditions of mining tunnel; but the principal stress distribution transits from compressive stress centralized in mining tunnel sidewall to tensile stress centralized in mining tunnel vault and floor.

研究结果表明，围岩条件不同的采矿巷道其二次应力分布影响范围有所差异，但围岩主应力总体上表现为由巷道边墙中下部位的压应力集中带逐步过渡到拱顶、底板一定范围内的拉应力集中带。

In this paper, commonly used "highway tunnel design specifications"(JTG D70-2004) in the BQ surrounding rock mass classification methods and geomechanics classification method on the highway翻坝increase the tiger to the right tunnel surrounding rock classification, and the following major conclusions

本文结合国内常用的《公路隧道设计规范》（JTG D70—2004）中BQ围岩分级方法和岩体地质力学分类方法对翻坝高速公路老虎岭隧道右幅进行围岩分级，并得到以下主要结论

The favorable conditions for petroleum accumulation due to volcanic activity and igneous rocks formed during the activity show in two aspects. A The contact surface of igneous rocks and the surrounding sedimentary rocks, like a vertical unconformity surface, formed the conduit of petroleum migration.Petroleum would accumulate once it encountered a trap in which the reservoir had fine porosity and permeability. B It formed a trap barriered by igneous rocks, or changed or cut the original trap.

火山活动以及由此形成的火成岩体对油气聚集的有利条件主要体现在两个方面：一是沿火成岩与围岩的接触面构成油气运移的通道，火成岩与围岩接触，似一直立的不整合面，与孔渗性好的岩层组合不仅能使油气运移而且遇有圈闭油气还会聚集成藏；二是构成火山岩遮挡的圈闭，或是对原有圈闭进行改造、分割。

Based on analysis of stress distribution in the wall rocks of underground opening and with the theory of slip line field s and Mohr Coulomb criterion, the characteristic of the plastic failure of the wall rocks has been studied.

在讨论地下围岩应力分布的基础上，用滑移线场理论和Mohr－Coulomb准则研究了地下洞室围岩进入塑性破坏状态的特征，推导了岩块沿滑移线滑落的条件，得到了岩爆发生时地应力的计算公式。

The results show that the pipe grouting changes the mechanical parameters of surrounding rocks to achieve the security of engineering objectives by reinforcing surrounding rocks and bolcking the water.

研究表明：小导管注浆一方面改变了围岩的力学参数，另一方面利用浆液的固结特性可以实现堵水和加固围岩的工程目标，使隧道在开挖过程中的安全得到保障。

The uniform standard of rocky and soil surrounding rock sub-classification built by self-stability span has rationality and inheritance.

可见，以自稳跨度可以建立岩质围岩和土质围岩统一的亚级分级标准。

Vertical and horizontal surrounding rock pressure can be determined by the statistic analysis of actual measured data.

依据实测围岩压力的垂直与水平分量沿隧道跨度与高度方向的统计规律，确定垂直方向与水平方向围岩压力的计算图式。

In the paper, the typical collapse and cavein incidents are listed, the treatment countermeasures, treatment process and treatment effects are presented, the experience and lessons in the tunnel construction are summarized and some recommendations are made.

由于大气降水、围岩渗水致使围岩缺乏自稳性，造成隧道连续大规模坍方冒顶，并列举典型事例，介绍事故处理措施、过程和效果，对施工中的经验教训进行了归纳总结，提出一些看法和建议。

The relationship between mantle fluid and U ore-forming was studied preliminarily,according to the results,the author considered theΣCO_2 of mineralizer and heat source came from mantle,which is because upwelling mantle forced by crustal extention and deep-seated faulting produced melt blending with lower crust,during this process,mantle provided the heat and releaseΣCO_2 to crust through outgassing.U mainly came from mantle-curst fluid formed by mantle-curst melt blending and the wall rock during fluid uplift.H_2O mainly generated from mantle fluid and the wall rock during mantle fluid uplift,and partly from atmospheric water in the late period of ore-forming.

初步探讨了地幔流体与铀成矿作用的关系，认为矿化剂∑CO_2和热源来源于地幔，是地壳拉张和深大断裂活动导致部分熔融地幔上涌，与下地壳产生壳幔混熔作用，在混熔过程中提供热量和向地壳&去气&释放∑CO_2；U主要来源于壳幔混熔形成的壳幔混合流体和流体上升途经的围岩；H_2O主要来源于地幔流体、地幔流体上升途经的围岩，在成矿晚期有部分来源于大气降水。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
