【摘要】：Hardfill壩型具有水化熱低、安全性高、抗震性好、對(duì)地基條件要求低等特點(diǎn),具有很強(qiáng)的適應(yīng)性和極高的推廣價(jià)值。在對(duì)這種新壩形開(kāi)展模型試驗(yàn)時(shí),受模型試驗(yàn)的限制一般不對(duì)揚(yáng)壓力進(jìn)行模擬,這樣必然會(huì)對(duì)試驗(yàn)結(jié)果產(chǎn)生一定影響。采用數(shù)值模擬來(lái)分析揚(yáng)壓力對(duì)于壩體的影響,從而考察模型試驗(yàn)中不考慮揚(yáng)壓力對(duì)試驗(yàn)結(jié)果的影響。結(jié)果表明,揚(yáng)壓力對(duì)壩踵處應(yīng)力值影響較大,對(duì)于其他點(diǎn)的變位和應(yīng)力值,差異均在10%以內(nèi),揚(yáng)壓力的綜合影響較小。
[Abstract]:The Hardfill dam type has the characteristics of low hydration heat, high safety, good seismic resistance and low requirement for foundation conditions. It has strong adaptability and high popularization value. When the model test is carried out on this new type of dam, the uplift pressure is generally not simulated under the limitation of the model test, which is bound to have a certain influence on the test results. The influence of uplift pressure on dam body is analyzed by numerical simulation, and the influence of uplift pressure on test results is investigated. The results show that the uplift pressure has a great influence on the stress value at the dam heel, and the difference for the displacement and stress values of other points is less than 10%, and the comprehensive influence of the uplift pressure is relatively small.
