摘要：多面体混凝土预制块其有体积大、重量重、易于预制、取材方便、生态环保、抗冲能力强、能快速对堵决口等优点，近年来在防汛堵口抢险工程中逐步得到应用.基于此，结合城市内河河流特征，对一种四校台状多面体混凝土预制块进行了构件形状设计、水流冲击力计算、抗冲击力计算和稳定系数计算并给出了应用于决口对堵工程实际的自重分别约为.0t和.61的四棱台状多面体混凝土预制块的2个构建方案及其造价，可供河湖提防决口封堵抢险工程参考

Ab trct : Polyhedral prefabricated concrete blocks are a kind of new technology for the flood prevention and levee breach closure with good characteristic of bulk mass , heavy weight easy precasting convenient material drawing ece friendly protection ,strong anti -scouring and fast levee breach closure , In recent years , polyhedral prefabricated concrete blocks are used for flood prevention and levee breach closure step by step with good application effect . Therefore , on the base of the intensive study on the characteristics of city inland rives , the paper carries out the shape design , the calculation for the im-pact of the current against the shore , the calculation for the impact resistance and the calculation for the stability coefficient for the polyhedral prefabricated concrete blocks in quadrangular frustum pyramid . Two construction plans and two kinds of construction cost have been put forward for the polyhedral prefabricated concrete blocks in quadrangular frustum pyramid with the weight of 1 ton and 2 ton. The study results of the paper can provide some references for the flood prevention and levee breach closure.

决口.堤防发生决口水毁的过程中选择适当时机对口门进行封堵称为堵口，一直以来河湖堤防决口封堵抢险中多采用直接抛石和铅丝笼、竹笼装石或大体积沙袋抛堵等传统方式但这些堵口抢险材料需要外部调运、现场装填，施工强度大、作业难度高，而且由于单体重量小、无法岸上联结成整体，致
