Conclusions Additional detailed investigations of the foundation of the Khudoni arch dam performed at the detail design stage made it possible to refine the engineering-geological structure of the rock mass in the foundation of the structure, to evaluate its stress state, and to determine the variability of the physical and mechanical properties of the rock under the effect of natural and technogenic factors. These investigations showed that the structure of the investigated mass is characterized by a greater complexity than was assumed at the contract design stage, and the relatively high characteristics of the physical and mechanical properties of the rock in the interior parts of the mass in many respects are due to the effect of natural (tectonic and gravitational) stresses. With considerations of the results presented, it is necessary to maximally preserve the natural state of the interior parts of the mass when correcting the working drawings and selecting the technology of construction works.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 2, pp. 44–49, February, 1990.  相似文献

1牛角峪概况 牛角峪退水闸位于漳卫南运河流域减河右岸,是恩县洼滞洪区的退洪口门,兼有排涝和蓄水灌溉,总洪水流量为378 m3/s.该闸1978年前由武城县水利局管理,1978~1980年由山东鲁北海河流域水利工程局管理,1980年后由漳卫南运河管理局德州河务处管理.漳卫南运河管理局接管该闸后,经检查发现许多隐患,如五孔闸运用时机架桥震动严重、无检修闸门、金属埋件锈蚀、闸门漏水、启闭机及电器部分年久失修等.为消除工程隐患和缺陷,确保水闸的安全运行,自1986年开始对以上诸多隐患分别进行处理,同时也加强了水闸运行管理.牛角峪闸每到汛期都要运用十几次至几十次,汛后开始闭闸蓄水.经维修后尽管运用比较频繁,也没有出现过任何事故,处于安全运行状态,较好地发挥了工程的经济效益和社会效益.  相似文献

Conclusion A comparison of the data of on-site observations of the state of the slope with the adopted criteria with respect to the position of the level of subsurface waters, absolute values of movements, and rates of movements leads to the following conclusion.The levels of subsurface waters in general meet the criteria, with the exception of levels In the gravel-sand deposits near the downstream slope of the dam of the upstream reservoir.The allowable value of total movement (taken equal to 50 mm) has been repeatedly exceeded on the north stretch of the site of the PW, where the movement, according to mark 207, reached 660 mm. Despite this, the diminishing character of deformations of the slope above the mark shows that the general stability of the slope has not been disturbed so far, and the noted movements have a local character. To ensure slope stability, it is necessary to take measures on lowering the water from the sub-Paramonova aquifer (in conformity with the design).The allowable deformation rates for periods of short-time transient work of the slope after filling the upper reservoir were also exceeded and amounted to 0.4–0.8 mm/day, but the mean monthly rates were 0.02–0.13 mm/day, i.e., did not exceed the allowable value of 0.15 mm/day.The steady-state rate of creep of 0.03–0.001 mm/day does not exceed the criteria.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 11, pp. 42–48, November, 1991.  相似文献
