断层位移测量是取得断层现今活动数据及探索地震前兆信息的重要手段。目前国内已在一些活动断裂布置了长期观察台网,有些测点是布置在断裂破碎带上。破碎带往往含有断层泥,断层泥的成分与原岩性质有关。断层泥中除原岩的破裂碎块及碎屑以外,常常还有一定数量的新生的粘土矿物。粘土矿物是伴随断裂活动而形成。粘土矿物种类繁多,性质各异,从膨涨性质来看,可分为膨涨和不膨涨两种。例如蒙脱石、柯绿泥石等 Fault displacement measurement is an important means to obtain the current active fault data and to explore the information of earthquake precursors. At present, some active faults have been arranged in China for long-term observation network, and some of the measuring points are arranged on the rupture zone. Broken belt often contains fault mud, fault mud composition and the original rock properties. In addition to the broken fragments and debris of the original rock in the fault mud, there are often a certain amount of newborn clay minerals. Clay minerals are formed with fracture activity. Clay minerals, a wide range of different nature, from the swelling nature of view, can be divided into swelling and swelling are not two. Such as montmorillonite, Ke chlorite and so on
