Abstract

Изобретение относится к устройствам измерения деформации, использующим в качестве чувствительного элемента оптическое волокно, с возможностью измерения распределения деформации оптического волокна в продольном направлении. Изобретение позволяет ограничить усилие, передаваемое якорем на сенсорный кабель, при смещении якорей друг относительно друга вызванного подвижками грунта вне зависимости от свойств грунта, которые могут быть известны неточно или меняться со временем, и за счет этого увеличить срок службы сенсорного кабеля. Устройство для измерения деформаций грунта содержит чувствительный к деформации сенсорный оптический кабель, измерительный блок, связанный с кабелем, якоря, связанные с кабелем и с грунтом, и снабжено системой защиты кабеля от разрушения, включающей встроенный в каждый якорь предохранитель.
