An Experimental Study on Increasing Effect of Bearing Capacity and Stiffness by Vertical Micropile

연직 마이크로파일의 지반 지지력 및 강성 증대 효과에 관한 실험적 연구

In this study, the reinforcing effect of micropile for weathered rock is analysed by laboratory model tests. Especially, the effect of the number, the surface roughness, and length of micropile are focused. The results of tests are as follows: $\circled1$ The deformation modulus of reinforced ground is less than equivalent deformation modulus, and $\circled2$ Increasing effect of unconfined compressive strength is not large as times as increasing the number of micropile.
