【Abstract】 The status of development and construction of the sand-gravel dam with clay core in Xinjiang is analyzed and summarized herein;in which the system of the key technologies for the construction of this kind of dam with the impervious soil materials of poor engineering properties under an unfavorable geological condition of relatively developed active faults within an earthquake zone prone to moderate to strong seismic activities is comprehensively and systematically summarized and then proposed.On the basis of this,the key technical system for the dam construction on active faults,including the technologies for control of deformation of dam body built with high compressive soil materials and the settlement difference between the main and the auxiliary dams,is studied and established;which not only provide an important technical guarantee for enhancing the safety of this kind of dam as well as its application and popularization,but also has a significance to raise the levels of both the construction and operation of the dam concerned.更多还原
