However, the coefficient of friction, <jats:italic>μ</jats:italic>, varies with degree of saturation and is not well constrained in the literature due to the difficulty of establishing fully drained or fully dried states in the laboratory. We measured <jats:italic>μ</jats:italic> of both saturated and oven‐dried montmorillonite at normal stresses up to 700 MPa. Care was taken to shear saturated samples slowly enough to avoid pore fluid overpressure. For saturated samples, <jats:italic>μ</jats:italic> increased from 0.10 to 0.28 with applied effective normal stress, while for dry samples <jats:italic>μ</jats:italic> decreased from 0.78 to 0.45. The steady state rate dependence of friction, (<jats:italic>a</jats:italic> − <jats:italic>b</jats:italic>), was positive, promoting stable sliding. The wide disparity in reported frictional strengths can be attributed to experimental procedures that promote differing degrees of partial saturation or overpressured pore fluid conditions.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004236852971650","@type":"Researcher","foaf:name":[{"@value":"C.
