Abstract
Compared with ordinary concrete anti-seepage walls,plastic concrete anti-seepage walls not only have good anti-seepage ability,but also can coordinate with the deformation of the surrounding soil.Due to the large size of hydraulic structures such as anti-seepage walls,considering the correlation between the mechanical properties of plastic concrete and its geometric size and shape,this study carried out an experimental study on the size effect of plastic concrete.The results show that as the size of the concrete bottom increases,the peak stress of the uniaxial compressive strength of plastic concrete decreases,the peak strain decreases,and the elastic modulus has no obvious change pattern.The correlation coefficient of the size effect model of plastic concrete peak stress is higher than 0.96 when fitting the peak stress,and higher than 0.8 when fitting the peak strain.The results can provide a reference for the size effect of plastic concrete.关键词
