Correct, the demolition of the gas valve is the gas valve from the spare machine work location, the body upperend in the jaws of a pair of pliers-bed of one side, the seat of the valve body with M8X 25 hexalobular heicobacter of hexalobular head alignment valve set's center position, hupensis the other side of the top in the jaw, to increase the contact area on the screw to prevent bursting valve set, at the same time makes it easy to remove.

气阀正确的，拆卸方法是，把气阀从机器工作位置拆下来，将阀体的一头放在钳台的钳口一边，阀体的阀座边用M8X 25内六角螺杆的内六角头对准阀套的中间位置，螺的另一边顶在钳口上，目的是增加螺杆的接触面积，防止顶破阀套，同时便于取出卡簧。

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 deformation compatible equation based on the catenary cable element is derived in chapter 2, and corresponding program is made to solve the accurate distribution of the prestress for cable dome. During the solving, two-nodes bar elements and catenary elements are adopted for the struts and cables of structure respectively. As the cable dome is a kinematically indeterminate system, its solving process is also derived in detail and the equations, which are based on large distortion, are adopted to solve the problem.

第二章推导了基于悬链线解析解的索单元变形协调方程式，并编制了相应计算程序对索穹顶结构精确的预应力分布进行求解，结构分析时压杆采用两节点直线杆单元，索采用悬链线索单元；考虑到索穹顶结构属于动不定结构体系，文中还对动不定体系的求解过程进行了详细的推导，同时采用建立在大变形基础上的变形协调方程来求解结构体系的有限机构位移。

Supporting the 8 inner stay bar with the top frame on around of the tower body as the same horizontal position, press the master chord of the tower body tightly, work in the tower head part of the climbing frame and adjust the vertical angle less than 4/1000 of the tower body.

A software for aided designing bolt of tunnel named ANSYSBOLT was designed on the basis of ANSYS finite element software. In the software environment, bolt supporting model of physical tunnel in tectonic stress field was structured according to physical parameters of coal and rock seam of some working face, and in conditions of different buried depth, bolt supporting structure and pre-tightening force, distributions of stress of surrounding rock of physical tunnel and its displacement were analyzed and calculated by ANSYSBOLT software. Then influence of different buried depth, bolt supporting structure and pre-tightening force on stability of roof and floor of tunnel was analyzed and finally feasible scheme of bolt supporting was gotten according to the analysis result.
