Kokhav Hayarden抽水蓄能电站上、下库坝坡抗震稳定分析
Seismic stability analysis on dam slopes of upper and lower reservoirs for Kokhav Hayarden Pumped Storage Hydropower Station
摘要
Abstract
According to the relevant requirements of international hydropower project,a seismic stability analysis is made on the dam slopes of both the upper and the lower reservoirs for Kokhav Hayarden Pumped Storage Hydropower Station in Israel.The peak value of acceleration,the design response spectrum of acceleration and the time-history input acceleration of the dam foundation surface upon a deep overburden are determined with the latest Israeli regulations SI413-2013 (English Version) for seismic design,and then the seismic safeties of the dam slopes of both the upper and the lower reservoirs built on a deep overburden under the conditions of the operational earthquake and the maximum design earthquake are rechecked with three normally used pseudo-static methods and the pseudo-dynamic method (i.e.Newmark sliding block method) recommended by the American Standard ASCE 7-05 and ICOLD,etc.It is known from the calculations on the factor of safety and the seismic sliding displace-ment under the conditions of various allowable sliding displacements that the dam slopes of both the upper and the lower reservoirs of Kokhav Hayarden Pumped Storage Hydropower Station can meet the engineering safety requirement of that the dam slope displacement under the operating basis earthquake (OBE) is less that 5 cm,thus the seismic designs of the dam slopes meet the specified requirements and the dam slopes of both the upper and the lower reservoirs have better seismic stabilities under the conditions of the operating basis earthquake (OBE) and the maximum design earthquake (MDE).The study result has an important referential value for the seismic design and safety assessment of the slope of earth-rockfill dam built on deep overburden in the international project concerned.关键词
