项目摘要
This research was analyzed in the following procedures about the measure when a crack arises to the core of a front core type dam, and acquired knowledge.Two-dimensional FEM examined the depth direction to a crack.Consequently, it turns out that a dam becomes danger, so that the crack was close to the reservoir surface of dam.The measure method of construction to the crack of a core was proposed.Validity of this measure method of construction was clarified in FEM and the experiment of sand model.It turns out that a measure method of construction suppresses a rise of the seepage line by the crack of a core, and a seepage line is drawn safely.It analyzed about the influence by the partial crack by 3-dimensional FEM.As for a rise of the seepage line projected also in the crack part, the crack near the reservoir surface of dam is not seen at about 10 %.If 70 % of the cross direction is exceeded, the effect of core of whole dam is lost and the seepage line of a homogeneous type dam is resembled.
本研究通过对前心墙坝心墙裂缝发生时的测量进行分析,获得了相关知识。二维有限元对裂缝的深度方向进行了检验。结果表明,大坝变得危险,裂缝靠近坝的库面。提出了心墙裂缝的施工测量方法。通过有限元和砂模型试验,阐明了这种施工测量方法的有效性。结果表明,施工测量方法抑制了心墙裂缝引起的浸润线的上升,用三维有限元方法分析了局部裂缝对坝体的影响,对于裂缝部位也投射出的浸润线,坝体库面附近未见10%左右的裂缝,超过70%的横向,整个坝体的心墙效应丧失,与均质坝的渗流线相似。
