The surrounding rock mass of the tgp shiplocks is jointed rock mass cut by well - developed discontinuous joints . the middle frusta and vertical border wall are the important components of the lock room construction . its deformability and stability will directly affect the construction function and using security 永久船闸区岩体属于一种断续节理切割的裂隙岩体,中隔墩和直立边墙是闸室结构的重要组成部分,其变形大小和稳定程度将直接影响三峡航道的结构功能和运行安全。
Abstract : in order to solve the roof leakage problems now widely exitst in buildings at home and abroad , this paper proposes the using of steel fiber reinforced polymer cement mortar concrete ( sfpcc ) as a rigid waterproofing roof material , based on that compounding polymer and cement helps improve construetion density of material . and both of polyer and steel fiber enable to enhance deformability of material . by testing elastic modulus , air shrindage and etc of sfpcc , this material is proved to be feasible in technology 文摘:针对目前国内外普遍存在的屋面防水问题,根据聚合物与水泥的复合物有利于改善材料内部结构密实度以及聚合物和钢纤维均能改善材料变形能力的特性,提出了用钢纤维增强聚合物水泥砂浆作为刚性屋面防水材料的设想,通过对钢纤维聚合物水泥砂浆的弹模、干缩等试验,论证了此种材料在技术上的可行性。
The results of experiments shows that core column can increase flexural and shear resistant capacity and improve deformability and entirety of composite walls ; it is coordinate ductility of two composite walls joining wire or steels out - of - plane ; the seismic of composite walls joining with wire is fine than joining with steels ; the deformation of out - of - plane only affect the crack - loading , the ultimate carrying capacity and ductility in - plane nearly has no change 墙片试验表明:芯柱可以增加复合墙体的抗弯和抗剪承载能力,改善墙体的变形能力和整体性;分别应用钢丝网片和钢筋连接的两种复合墙体的平面外延性大致相同,内外叶墙协同工作良好;内外叶墙之间的连接提高了外叶墙砂浆层抗拉强度,同时也提高了复合墙体向外叶墙方向的抗推和抗拉承载力。
