棉花滩水电站地下厂房设计 总被引:1,自引:0,他引:1
棉花滩水电站地下厂房安装4台水轮发电机组,总装机容量600MW。除了开关站出线场和控制楼布置于地面外,主厂房、主变室、尾水调压室及其他洞室均布置于地下,形成了一个错综复杂的大型地下洞室群。地下厂房的设计主要包括位置及纵轴线方向选择,洞室群及厂房内部布置、喷锚支护、结构设计等。实践证明,地下厂房的布置和设计是合理的。 相似文献

Conclusion The experience in constructing the underground machine hall in a frozen rock mass thawing during operation, just as of other underground structures at the Kolyma hydrostation, has great practical significance for consideration when designing and constructing underground structures under analogous conditions.The main requirements imposed on the creation of reliable underground structures having a large cross section under permafrost conditions are:Comprehensive consideration at the design stage of the engineering-geological, cryogenic, hydrogeological, temperature, and other conditions of the surrounding rocks, including the structure and initial stress state of the mass, established by specific experimental works;Substantiation of designs taking into account the change in the modulus of deformation and stress-strain state of the rock mass and conditions of performing the works;Creation of primarily yielding designs of the linings (support) able to absorb nonuniform loads without disturbing their continuity under conditions of specially constructed drainage systems for removing seepage waters;Thorough observations of the state of the rock mass during driving; in this case, a correct substantiation of the criteria making it possible to provide preservation of the enclosing rocks, structural members, and equipment from all types of effects with consideration of the stress-strain state of the structure is important.On-site observations, investigations, and calculations confirmed the sufficient effectiveness of the strengthening measured performed on the arch of the machine hall of the Kolyma hydrostation. The on-site observations should be continued until complete stabilization of movements in the arch and surrounding rocks over the entire contour of the hall chamber.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 5, pp. 24–29, May, 1990. 相似文献

1. | For underground machine halls with a large number of units the areas of the assembly floors should be 1.5–2 times greater than for outdoor hydrosation powerhouses. Zones of the MH adjacent to the vehicular tunnels cannot enter into these areas; these zones should be regarded only as loading areas. |
2. | The technology of excavating the underground machine hall, including pits for the draft tubes, introduced at the Hoa-binh hydrostation can be recommended for excavating large chambers of considerable length. |
3. | The use of the given technical solutions when constructing underground hydroelectric station and pumped-storage stations in combination with fulfillment of par. 1 of the “CONCLUSIONS” will make it possible to reduce considerably the total construction time of underground machine halls and to provide start-up of all units. |

以某抽水蓄能电站地下厂房为工程实例,采用有限元法,建立地下主厂房与副厂房的耦联体系,对副厂房进行了自振特性和共振复核的分析计算。通过改变主副厂房间结构缝填充材料的物理力学参数,并以楼板的振动响应为依据,探讨了抽水蓄能电站地下主副厂房间振动传递的途径和规律。结果表明,副厂房楼板的振动大部分依靠围岩传递;当结构缝填充材料弹性模量较大时,在高频流道脉动压力作用下,与荷载作用位置较近的副厂房楼板的纵向振动主要通过结构缝的填充材料进行传递。研究所得相关结论为副厂房楼板的隔振减振提供有力依据。 相似文献
