Aim for the topic - study of prestressed lightweight concrete platform , from selecting style of the platform , to matching concrete material and admixture , to designing and building the model , to carrying out experiments of temperature field and stress performance , and analysis of finite element , some research work have been done as follows : 1 本文针对“轻质高强预应力混凝土平台的研究”这一课题，从罐体结构型式的确定，混凝土基本材料及外加剂的选配，模型的设计制作，到模型结构在各种外荷载及温度荷载作用下的受力性能试验研究及罐体结构的有限元分析，展开了如下几个方面的研究： 1
Because the experimental bridge is an arcade bridge which is comprised of three four - arched bridges , micro - expansive lightweight concrete , micro - expansive ordinary concrete and ordinary concrete are used in each four - arched bridge respectively in order to comprehend the performance of light expanded lightweight aggregate concrete profoundly and contrast effects of different materials 为了更好地掌握轻质微膨胀砼的加固性能以及对比不同加固材料的加固效果，针对实桥为4孔1联，共计3联的特点，各联的加固分别采用了轻质微膨胀砼、普通微膨胀砼和普通砼三种不同材料。
Referring to the forms of floor solution abroad , autoclaved lightweight concrete ( alc ) floor used in low buildings and precast alc composite slab used in middle buildings are put forward . furthermore , the calculational methods and corresponding analyses are discussed . ( 4 ) research on design method of low light gauge steel constructions in north america 本文研究全工业化的轻钢龙骨体系在低、多层住宅中的结构性能，以结构体系创新为出发点，开展一系列理论研究，并以相应试验来检验理论分析结果，对推动轻钢龙骨体系在我国的应用具有理论和应用价值。
Being lightweight aggregate , the chemical mineral constituents and physical mechanics properties of lytag are analyzed . meanwhile properties of haydite concrete using lytag as coarse aggregate are also studied . the influences on lightweight concrete qualities by introducing wollastonite and chemical admixtures are researched which proves the important roles of wollastonite and admixtures in construction of concrete platforms 分析了作为轻骨料的粉煤灰陶粒的化学、矿物成分和物理力学性能以及用它作为粗骨料配制出的轻质混凝土的各项特性；研究了掺入硅灰和减水剂等外加剂对混凝土的强度、耐久性和新拌混凝土可工作性的影响；说明了硅灰和化学外加剂在海洋平台混凝土施工中不可或缺的作用。
