Operation and management of dam safety Tiemenguan Summary
Cheng Ping of the increase, our factory to ensure the safety barrier of the dam runs as a precondition. To as the standard \100% success rate. To promote the safe operation of the dam management work force continue to develop increased by 6 Conclusion I plant on the operation and management of dam safety review of what I plant the safe operation of power generation from the construction of 13a since,ugg boots günstig, in order to keep the development of power system to adapt to the needs of experienced and ten from the imperfect process of gradually improving. First of all, from the management on the basis of \management approach, \the dam safety in all aspects of strength were significantly improved; again, from the dam safety monitoring, finishing on observations Jishi, accurate analysis and computer calculation input checking, integration, analysis,ugg boots, improving the observation accuracy. In 200O in accordance with the \conduct a comprehensive review of debt were completed special report 9, the final assessment of the dam as a normal dam. but we should on this basis, the ongoing enhancement and improvement,moncler jackets, thus ensuring the long-term safety of the dam, and stable operation, so I plant Double standards across people as soon as possible \Ma set up the first row in the upstream channel (d 1042 m elevation), the second row set in the crest of wave wall (d 1050 m elevation), the third row set back in the downstream dam Horse Road (1039.O0m elevation】, the fourth row set foot in the downstream dam platform (1028O0m elevation). filling the dam to be completed from the beginning took nearly 4a, to start January 1972 l】 concept of vertical displacement of a formal side, the dam has been completed before the Long subsidence in 28a run subsequent observations. dam during vertical lines become flat bit Mu. vertical displacement of the characteristic values shown in Table 7. can be seen from the table. Upstream Ma, the maximum total settlement +110 Ⅱ handsome. minimum cumulative settlement +51 mm (1978 value on May 6, followed by the location of the measuring points for objective reasons,MBT Schuhe günstig, no longer be measured); crest wave wall maximum cumulative settlement +165 r / llll, minimum cumulative settlement +138 III/11; downstream dam Ma, the maximum cumulative lumbar +50 r canthal settlement, the minimum total settlement +33 rattt; foot dam downstream of the maximum total settlement platform, +37 mm, the minimum total settlement +】】 mm vertical displacement dam decreases year by year, increasing after 1981 stable, has been almost unchanged. 53 Dam Dam Fu penetration into the observed very little observational facilities. The original is only 3 .3 a piezometer piezometric wells. and without a complete cross-section, observations are not complete, imprecise. only as a secondary reference. piezometer tube and piezometer wells greater seepage water early, then hours gll in 1983 and 1981, dry wine 2O00 joy in June with the first periodic dam safety inspection, at 0 +080 and 0 +168 Stake re-arrangement of two rows of piezometers has invested a total of 6 using the 'osmotic flow observation to monitor the dam did not do the amount of the weir, the initial time is measured by current meter, the latter with natural dam big blanket with the formation of sludge, seepage getting smaller and smaller, with a current meter has been measured do not come out in November 1981 of basic drainage in the dry, it stopped the observations. from existing observations of view, osmotic pressure and seepage in the dam Xucheng initial large. then piezometer tubes (wells),Botas UGG Bailey Button, seepage of water and reduced year by year has been basically stable. 6 Conclusion Since 1972, power plant monitoring and management of the dam very seriously. As the United States iron core dam is a loam, gravel, shell hybrid dam dam, dam construction, not only to deal with the concrete cutoff wall, and construction quality control is better. With the dam the formation of a large blanket of natural mud, thick, impervious to change the status of the dam, dam leakage decreases year by year, gradually increasing the stability of the dam's safety. Power over the years observations show that the deformation of the dam Tiemenguan seepage has stabilized. 28a in the past, the dam has never been more significant, impact on the maintenance of the main project or reinforcement, have maintained good running condition.
