| 1 | 裂缝对有库水混凝土重力坝地震响应的影响显示文摘一、引言 对于混凝土重力坝,强烈的地震地面运动会在坝体内产生超过混凝土抗拉强度的应力,从而导致混凝土裂缝的形成和扩展,削弱某些部分坝体。这将影响混凝土坝的动力性能,即开裂坝体的响应将明显地区别于未开裂坝体的响应。精确预测裂缝形成的动力学特性,对可靠地评估受地震地面运动作用的坝的安全性是至关重要的。 | G.Feltrin M.Galli H.Bachmann 杜成斌 | 1994 | 世界地震工程1994，10，2： | 1 |
| 2 | Armoured mud balls as a result of ephemeral fluvial flood in a humid climate:Modern example from Guizhou Province,South China显示文摘Armoured mud balls were observed after rainfall and a short flood in the otherwise dry Xiaohe(small river) valley of Guanling County,Guizhou Province,South China,approximately 30 km southwest of Guanling City.Armoured mud balls are most common in semiarid climates,but rather unusual in a humid climate as in Guizhou.A number of well-rounded mud balls,2-20 cm in diameter,were found lying on the gravel of the Xiaohe gully floor.The mud balls consist of sticky,light brown and slightly mottled clay without carbonate content.The surfaces of the mud balls were studded with rims of sand- or gravel-size limestone clasts,collected during bedload transport,as is typical for armoured mud balls.The mud balls originated from alluvial mudstone deposits of the valley floor and cliff that are most likely derived from the weathering and karstification of bedrock limestones.Such mudstones seem to be especially well suited for forming armoured mud balls.As flood events are rather common in the area,the formation of armoured mud balls should be very frequent in the Xiaohe valley and similar valleys nearby,giving the possibility for further and more detailed studies.To the best of our knowledge this is the first description of armoured mud balls in China. | Gerhard H.Bachmann | 2014 | Journal of Palaeogeography2014，3，4： | 0 |
| 3 | 裂缝对有库水的混凝土重力坝地震响应的影响显示文摘1 引言 对于混凝土重力坝,强烈的地震地面运动将会在坝体内产生超过混凝土抗拉强度的应力区域,从而导致混凝土裂缝的形成和扩展,削弱了结构的作用。而且将影响混凝土坝的动力性能。 迄今为止,已有好几个模型被用于混凝土重力坝的非线性动力分析。 | G.Feltrin M.Galli H.Bachmann 杜成斌 | 1994 | 河海科技进展1994，14，3： | 0 |
