摘　　要：通过对采用2种构造措施和未采取构造措施的混凝土小型空心砌块单片墙体进行的对比试验 ,了解到具有不同构造措施的墙体初始裂缝的开展部位、裂缝形态、发展规律和墙体破坏形态 ,确定了不同构造措施墙体的抗裂荷载和极限荷载 ,明确了芯柱和构造柱在提高混凝土小型空心砌块墙体的抗裂荷载和极限荷载方面的作用 。The initial cracking position, cracking shape, developing law and wall broken shape for different constructural measurement walls were found out by means of comparison test using single leaf walls of small concrete hollow blocks with two constructional measurements and without this measurement. The cracking resistant load and ultimate load for different constructural measurement walls have been fixed. The actions of core and constructural columns increasing cracking resistant load and ultimate load for small concrete hollow block wall have been made clear so that the theoretical basis are provided so as to ensure cracking resistant result for this kind of wall.
