This paper mainly discusses the design and construction of the supporting soilbolts used in structure for bulkhead walls or slope-supporting bolts and walls under pressure.

本文主要介绍作为工程结构中挡土壤或护坡桩、墙,受土压力作用下支承锚杆设计与施工中的一些经验体会。

Systematically analysis is given of the models for two kinds of clamping forces calculation, which are governed by supporting bolts for fixing blocks and supporting plates when the box type parts are being positioned with plane reference. Again in the paper, the methods of the clamping forces calculation under four situations are proposed on the basis of the acting point exerted by the clamping force in relation to the supporting barycenter to be found if the both in question is in coincidence...

Systematically analysis is given of the models for two kinds of clamping forces calculation, which are governed by supporting bolts for fixing blocks and supporting plates when the box type parts are being positioned with plane reference. Again in the paper, the methods of the clamping forces calculation under four situations are proposed on the basis of the acting point exerted by the clamping force in relation to the supporting barycenter to be found if the both in question is in coincidence or not.

系统地分析了箱体类零件以平面定位基准定位时,定位元件支承钉和支承板两种夹紧力的计算类型,并根据夹紧力作用点与支承重心的重合和不重合,提出四种情况下的夹紧力计算方法。

The paper presents uniform method of evaluation mining geological and technological conditions for application of rock bolting in Polish underground coal mines. The formulas for obtaining strength and strain parameters of rock mass are described using modified index RMR of rock mass quality. The numerical model of roof bolting and rock mass collaboration was based on Hoek Brown's strength criterion. Several cases of roof bolting application in various mining and geological conditions were described. The conclusions...

The paper presents uniform method of evaluation mining geological and technological conditions for application of rock bolting in Polish underground coal mines. The formulas for obtaining strength and strain parameters of rock mass are described using modified index RMR of rock mass quality. The numerical model of roof bolting and rock mass collaboration was based on Hoek Brown's strength criterion. Several cases of roof bolting application in various mining and geological conditions were described. The conclusions are drawn from the experiments carried out so far on roof bolting application in coal mines. It was assumed that the safest method is the use of support bolt lining initially and then applying individual roof bolting.

针对波兰煤矿地下开采中的锚杆支护应用实践 ,提出了统一的采矿地质和技术条件的评价方法。用修定的RMR岩体量化指数从给定公式中确定岩体强度和应变参数。基于虎克 -布朗强度准则给出了岩体及顶板锚固的数值模型。在不同的采矿地质条件下 ,进行了多种顶板锚固应用研究。这些支护实验表明 :这种方法应用于巷道的初次支护和顶板加强支护是安全可靠的
