Based on an in-situ measurement of time dependence of displacement in tunnel, a new model, describing the rheologic behavior of viscoplastic country rock is developed. The model consists of two Hookean solids, a Newtonian fluid and a plastic body, and it is shown that the well-known Poynting-Thomson body is just a particular case of it. With the state equation of the model introduced, the reaction of support in a circular cross-sectional tunnel and peripheral displacement of tunnel are solved under conditions...

Based on an in-situ measurement of time dependence of displacement in tunnel, a new model, describing the rheologic behavior of viscoplastic country rock is developed. The model consists of two Hookean solids, a Newtonian fluid and a plastic body, and it is shown that the well-known Poynting-Thomson body is just a particular case of it. With the state equation of the model introduced, the reaction of support in a circular cross-sectional tunnel and peripheral displacement of tunnel are solved under conditions of hydrostatic pressure. Basic characteristics of the inherent field stress exerting to viscoplastic country rock are indicated with several shaft supporting methods recommended, ie. the telescopic shield, rigid lining, soft rock strengthening by grouting or using anchorge bars.

本文根据现场实测位移-时间曲线,建立一种新的围岩粘塑性流变模型。该模型由二个虎克体,一个牛顿体和一个塑性体组成。常见的Poynting-Thomson体仅是它的一个特例。利用该模型的物态方程解出了静水压力下圆形巷道的支护反力和巷道周边位移。指出了粘塑性软岩地压的基本特征和支护方法。

Bolting, as a very effective and relatively cheap support method, was applied for support of mining structures, halls, tunnels, roads, and rail cuttings, dam foundations, etc.. In design and application of the bolt system, the mechanism study of the bolt is significative. In the present paper the mechanism of the full-column resin grouted bolt is discussed.This paper is concerned with the diffusion of an axial load along the bolt, the shear force acting on the rock mass and the additional stress...

In design and application of the bolt system, the mechanism study of the bolt is significative. In the present paper the mechanism of the full-column resin grouted bolt is discussed.This paper is concerned with the diffusion of an axial load along the bolt, the shear force acting on the rock mass and the additional stress and displacement fields developed in the rock surrounding the excavation by the shear forces. A method for choosing the parameters of the rockbolts is discussed also. All formula were obtained about an circular opening.

在地下工程中,锚杆支护是一种有效的、低成本的支护手段。各国都十分重视锚杆支护机理和设计方法的研究工作。本文对全长固定式锚杆作了一些理论探讨。 文中讨论了锚杆轴向力分布、岩体所受剪力以及剪力作用下的锚杆附加应力场、位移场的特点。并指出在硬岩和软岩中锚杆支护机理是不同的。锚杆与围岩的弹模比对支护效果有重要影响。 文中给出了锚杆支护参数的选择方法。

Stress analysis of the entire stress field is made by photo-elastic method with a model of self-supporting rock ring in a roadway. Comparisons of several types of self-supporting ring are made, such as those' with round holes, with 6 slots and secondary stress relief slots, etc. The data obtained from photo-elastic analysis are used directly for calculating the internal stress in the stress field with a boundary element method to replace the conventional shear stress differential method, and as a result, errors...

Stress analysis of the entire stress field is made by photo-elastic method with a model of self-supporting rock ring in a roadway. Comparisons of several types of self-supporting ring are made, such as those' with round holes, with 6 slots and secondary stress relief slots, etc. The data obtained from photo-elastic analysis are used directly for calculating the internal stress in the stress field with a boundary element method to replace the conventional shear stress differential method, and as a result, errors are greatly reduced. The results of experiments have indicated that the peak stresses originally concentrated on the walls of boreholes have moved inwards, which resulted in removal of concentrated loads on the walls of boreholes. This has proved the feasibility of replacing the conventional roadway supporting method by a self-supporting rock ring in the roadway.

本文用光弹分析方法对巷道自支撑岩石环的模型进行了全场的应力分析。对几种形式的自支撑岩石环进行了比较,有圆孔、六槽和二次卸载槽等。并直接由光弹信息用边界元法计算应力场内部应力,代替传统的切力差法,使误差大为减少。实验结果表明,原来集中在孔壁的应力峰值向岩体内转移,达到了卸去孔壁集中载荷的目的,从而证实了用巷道自支撑岩石环代替传统的巷道支撑方法的可行性。
