This study uses plate shear instrument that can produce a plate shear and record both torsion and settlement simultaneously. Radius of specimen ring is 10 cm. Height of the specimen is 10.5 cm. The plate shear tests were carried out with initial relative densities 30%. Fine contents 5%~35% of Mai-Liao sand , fine contents 0%、20% of Vietnam-sand, fine content 0%、18% of Ottawa-sand. Reversal and one-way shear, normal stresses 7 kPa~100kPa.To measure settlement and try to get a relative density and to measure cone resistance value after plate shear.

本研究系利用可施加盘转剪力并同时记录扭力与沉陷的圆盘剪力仪进行实验，土样环半径为10 cm，土样高度为10.5 cm，初始相对密为度为30%、细料含量为5%~35%之麦寮砂、0%及20%之越南砂、0%及18%之标准砂，进行单向及往复式盘转剪力试验，载重为7 kPa~100 kPa，试验后量取沉陷量，求得盘剪后之相对密度，并量测盘剪后之圆锥贯入阻抗值。
