摘要

摘要：为了确定在审查巴尔瓦宾坝址密封帷幕的设计和执行过程中所需的灌浆操作参数，在河床中的一部分密封帷幕区域进行了试验灌浆操作。根据坝基区域不连续性的特性，在垂直和成角度的行中进行试验灌浆，以与最大不连续性相交。之后，对获得的结果进行了分析，最后，由于10米以上深度的岩体不可灌浆，并且根据基础中存在的外围廊道，密封灌浆操作被推迟到下一次脱水。大坝脱水后的测量表明是否需要灌浆或可以取消灌浆。在灌浆廊道可用的情况下，可以在任何其他时间进行灌浆。

Seal grouting operation of slate and schist rock masses of Zanjan Balvabin Dam site, Northwest of Iran

ABSTRACT To identify the required parameters of grouting operations in scrutinising the design and execution of seal curtain of the Balvabin dam site, the test grouting operations were conducted in a part of the seal curtain zone located in the riverbed. The test grouting was carried out in the vertical and angled rows according to the properties of discontinuities in the dam foundation zone to intersect the maximum discontinuities. Afterwards, the obtained results were analysed and finally due to the not groutable of the rock mass at the depths of more than 10 metres and according to the presence of peripheral gallery in the foundation, the execution of seal grouting operations was postponed until next dewatering. The measurements after the dewatering of the dam indicate whether grouting is required or it can be eliminated. With the grouting gallery being available, the grouting can be carried out at any other time.

期刊介绍： Geomechanics is concerned with the application of the principle of mechanics to earth-materials (namely geo-material). Geoengineering covers a wide range of engineering disciplines related to geo-materials, such as foundation engineering, slope engineering, tunnelling, rock engineering, engineering geology and geo-environmental engineering. Geomechanics and Geoengineering is a major publication channel for research in the areas of soil and rock mechanics, geotechnical and geological engineering, engineering geology, geo-environmental engineering and all geo-material related engineering and science disciplines. The Journal provides an international forum for the exchange of innovative ideas, especially between researchers in Asia and the rest of the world.
