At present, one problem exisiting in the theory about the evaluation of the stability and the methods of calculation for surrounding rock of tunnel is that the structure design is disjointed to a certain extent from the geological works. The purposes in this paper are to obtain the formulas for discussing the stability, calculating the earth pressure, the safe joint-span ratio curve for discussing the stability of the surrounding rock and the formulas of the shotcrete-bolt lining design.

At present, one problem exisiting in the theory about the evaluation of the stability and the methods of calculation for surrounding rock of tunnel is that the structure design is disjointed to a certain extent from the geological works. The purposes in this paper are to obtain the formulas for discussing the stability, calculating the earth pressure, the safe joint-span ratio curve for discussing the stability of the surrounding rock and the formulas of the shotcrete-bolt lining design. These formulas are solved by the methods of rock mechanic theory and contain the elements such as the texture of surrounding rock, the natures of rock, the mechanical properties of the structure planes and the geometric dimensions of the tunnel. Therefore the problem as pointed out in upper the structure design is disjointed from the geological works shall be solved to a certain extent.

当前,有关地下洞室围岩稳定性评价理论和围岩压力的计算方法存在着一些问题,其中之一就是设计工作和地质工作有脱节现象。本文目的是把围岩岩体结构、岩石性质、结构面力学特性及洞室几何尺寸等因素,用岩石力学方法求得包括围岩隙跨比在内的判别围岩稳定性的鉴别公式、判别毛洞围岩稳定性的安全隙跨比曲线、计算围岩压力和设计喷锚结构的计算公式。这些公式由于包括了围岩岩体结构特征和洞室几何尺寸在内,因而在一定程度上有助于解决上述设计工作和地质工作脱节的现象。

Two coupled formulae between mechanical and hydraulic parameters of a structural surface are presented in this paper. Study of the hydromechauics of a structural surface by means of modelling test is described. The characteristics of seepage flux change in Gezhouba Sluice Foundation on the Second River is analysed according to these two formulae. The research results show that they lare the basis to study and predict the hydraulic characteristics of rock mass, and to carry out rock mass hydraulics analysis.

Recently,the author has paid much attention to the characteristic sha- pes of the fluid inclusions,their grouping and their relation to the tectonic stress field during their formation.It is well known that the primary inclu- sions could record the temperature,pressure,density and concentration of the fluids at the time when the minerals and rocks were formed.In this paper,it is shown that the characteristic shapes of the fluid inclusions and their grouping pattern could also reflect to some extent the stress...

Recently,the author has paid much attention to the characteristic sha- pes of the fluid inclusions,their grouping and their relation to the tectonic stress field during their formation.It is well known that the primary inclu- sions could record the temperature,pressure,density and concentration of the fluids at the time when the minerals and rocks were formed.In this paper,it is shown that the characteristic shapes of the fluid inclusions and their grouping pattern could also reflect to some extent the stress state pre- vailing during their formation.Secondary inclusions definitely oriented along structural fissures were produced in response to the tectonic stress together with the change of minerals and rocks.Thus,it is safe to say that both the primary and secondary inclusions are connected to the deformational and metamorphic events of the rocks. Fluid inclusions usually occur in a definite pattern,such as S-shape,- shape,x-shape or others.Such shapes may be probably a reflection of a com- pressive or a shear stress state,whereas a flask-shape may suggest a ten- sile stress state.Furthermore,an estimate of the depth and environment of the reworking of rocks can be made from the temperature and pressure at which the inclusions were formed.

流体包裹体常成群出现,定向排列,成带分布,且有特定形态和组合规律。作者以郯庐断裂带的三里同构造剖面中的流体包裹体研究为例,说明研究流体包裹体群的形态和组合规律,有助于结构面力学性质的鉴定,也有助于分析应力活动的方式和方向。
