The test results obtained accor- dingly are presented in this paper .Three stopes with different spans (8m , 16m, 24m ) were selected for the purpose of stress study with epoxylite model .

采用环氧树脂模型研究了三种不同跨度(8米、16米、24米)采场，在支护网度为1×0.8米~2及无锚杆护顶时顶板应力分布状况，同时也研了在相同条件下，锚杆支护网度为0.8×0.8米~2、1.6×0.8米~2时顶板应力分布状况，从而阐明了锚杆支护的实际效果。

The studies also show that the increased supporting force can reduce the radius of the fractural zone in surrounding rock derectly, but the main effect of the increased supporting force is to improve the compressive stress on rock in elastoplastic region, and to increase the rock strength of whole fractural zone so as to reduce the scope of fractural zone.

而当围攻岩中出现了塑性区和破裂之后，支护力的作用才开始显现。提高支护力可直接减小围岩破裂区范围，但提高支护力的主要作用是提高弹塑性区围岩压应力，达到提高破裂岩体宏观强度的目的，从而减小塑性区和破裂区的范围。

The common suspension roof support without pre-stressing based on the constant stress field is no longer safe for such engineering. Recently, the popular and receptible supporting form is high-strength pre-stressed bolting with resinic anchoring agent for the deep underground engineering.

基于浅部常应力场的普通非预应力锚杆支护已不能满足此类工程的安全性要求，以树脂药卷作锚固剂的高强、超高强预应力锚杆支护应属于目前最能符合此类深部地下工程的支护形式。

Based on excavation and supporting conditions of soil nail structures,it is simulated and analyzed that internal force of the siol nail in excavation and support processes.

采用三维显式快速拉格朗日法(FLAC3D)从土钉支护的作用机理出发，结合某基坑土钉支护实例，对土钉在开挖支护过程中的内力进行了模拟分析，并将模拟结果与理论计算结果和监测结果进行了对比，三种结果基本吻合，得出了土钉内力的分布规律。

Practice of advance grouting of pump house in Hexi Gold Mine;2. The method of pipe anchor of advance grouting is adopted to avoid flowing sond and piping It argues the mechanism of advance grouting in waterproof and reinforcement.

本文介绍了在基坑喷锚支护工程中，采用锚管预注浆法对基坑边坡进行超前支护，防止流砂及管涌，并对预注浆法的止水及加固机理进行了探讨，分析了浆液在砂土层中的扩散及胶凝等过程，通过土方开挖验证了注浆效果，使喷锚支护能够顺利进行。

Three stopes with different spans (8m , 16m, 24m ) were selected for the purpose of stress study with epoxylite model . The distributions of roof stress under the condition of 1×0.8m support grid compared with unsupporting , and that of roof bolting patterns of 0.8×0.8m, 1×0.8m, 1.6×0.8m were also investigated . Finallg , the authors evaluate the practical effects of roof ?

采用环氧树脂模型研究了三种不同跨度(8米、16米、24米)采场，在支护网度为1×0.8米~2及无锚杆护顶时顶板应力分布状况，同时也研了在相同条件下，锚杆支护网度为0.8×0.8米~2、1.6×0.8米~2时顶板应力分布状况，从而阐明了锚杆支护的实际效果。
