［摘要］為探究地下綜合管廊腋角高度、建造方式對(duì)管廊結(jié)構(gòu)加速度、層間位移、鋼筋應(yīng)變影響，完成管廊模型地震響應(yīng)振動(dòng)臺(tái)試驗(yàn)。設(shè)計(jì)4個(gè)相似比為1/6的管廊模型，在El Centro波作用下通過(guò)輸入不同的頻率、幅值，研究不同參數(shù)對(duì)管廊動(dòng)力響應(yīng)影響。研究結(jié)果表明：增大腋角高度對(duì)管廊結(jié)構(gòu)加速度的作用易受到管廊結(jié)構(gòu)本身及周圍土體非線性的影響；腋角高度對(duì)裝配式管廊影響大，增大相同腋角高度裝配式管廊結(jié)構(gòu)的層間位移降低30%～50%，而整澆式管廊降低10%～30%；在強(qiáng)震時(shí)建造形式對(duì)加速度及管廊頂板、底板的層間位移影響均較大；增加腋角高度，兩種管廊鋼筋應(yīng)變均變小，裝配式管廊變化大；裝配式管廊鋼筋應(yīng)變大于整澆式管廊鋼筋應(yīng)變。

Abstract:In order to explore the influence of the height of the corner widening height and the construction method of the underground comprehensive pipe gallery on the acceleration, story displacement and reinforcement strain  of the pipe gallery structure, the shaking table test of the seismic response of the pipe gallery model was completed. Four pipe gallery models with the similar ratio of 1/6 were designed. The effects of different parameters on the dynamic response of pipe gallery were studied by inputting different frequencies and amplitudes under the action of El Centro wave. The results show that  the effect of increasing the corner widening height on the acceleration of the pipe gallery structure is easily affected by the nonlinearity of the pipe gallery structure and surrounding soil; the  corner widening height has a great influence on the fabricated pipe gallery, by increasing the same corner widening height, the fabricated pipe gallery displacement decreased by 30%~50%, while the whole casting pipe gallery displacement decreased by 10%~30% ; in the case of strong earthquake, the construction method has a great influence on the acceleration and the floor displacement of the top and bottom of the pipe gallery; when increasing the corner widening height, the steel strain of two kinds of pipe gallery became smaller and the fabricated pipe gallery changed greatly; the steel strain of the fabricated pipe gallery is larger than that of the whole casting pipe gallery.

Keywords:fabricated pipe gallery； whole casting pipe gallery； construction method; corner widening height; shaking table test; dynamic response
