在恒定的正应力和孔隙压力、不同温度下测量了三种蛇纹石断层泥摩擦强度的速度依赖性。在室温下，纤蛇纹石具有很低的摩擦系数（０．２～０．２５），而利蛇纹石和叶蛇纹石的摩擦系数较高，分别为０．３９和０．４５左右。在２５～２００℃范围内，温度变化对纤蛇纹石和叶蛇纹石强度的影响不明显，而利蛇纹石的摩擦系数随温度升高明显增加。室温下，三种蛇纹石的摩擦在较快的滑动速率下表现为微弱的速度弱化，而在较慢的滑动速度下为明显的速度强化，温度的提高有促使速度弱化向速度强化转变的趋势。研究表明，蛇纹石的存在有利于断层的无震蠕动，但这种影响可能主要限于浅部；尽管纤蛇纹石是最软弱的造岩矿物之一，但仍不足以解释圣安德烈斯断层的软弱性
The velocity dependency of the frictional strengths of the three serpentine cuttings was measured at constant normal and pore pressures at different temperatures. Chrysotile has a very low coefficient of friction (0.2-0.25) at room temperature, while the coefficient of friction for both leucrose and leaf serpentine is about 0.39 and 0.45, respectively. In the temperature range of 25 ~ 200 ℃, the influence of temperature on the strength of chrysotile and leaf serpentine is not obvious, while the friction coefficient of the serpentine increases with temperature. At room temperature, the friction of the three serpentins shows weak weakening at higher sliding velocities, while at slower slip velocities it is evident that the friction of the serpentine increases obviously with the increase of temperature trend. Studies have shown that the presence of serpentine favors the earthquake-free creep of the fault, but this effect may be mainly confined to shallow depths. Although chrysotile is one of the weakest rock-forming minerals, it is not enough to explain St Andre The weakness of the fault
