钻孔倾斜仪在某堆积体变形监测中的应用

The application of borehole inclinometer in the monitoring of accumulation body's strain

指出钻孔倾斜仪是一种测定钻孔深部位移的原位监测仪器,在堆积体变形监测中有着广泛的应用,根据监测成果,认为该堆积体的变形机制为蠕滑—拉裂型,地震后,堆积体并未失稳,表明堆积体有吸收强地震能量的能力,但地震会使堆积体的变形更为明显,开挖堆积体形成的边坡仍然需要强有力的支护。

Borehole inclinometer is a monitoring instrument in situ to measure lateral displacement of borehole, and the instrument has an extensive application in the monitoring of accurnulation body＇s strain. According the monitoring ressult, the deformation mechanism of the accu- mulation body is thinked creep-tensile rupture model. The accumulation body didn＇t lost it＇s steady after the earthquake, which betrays that the accumulation body has the capacity of absorping strong earthquake＇ s energy. But earthquake will make accumulation body＇ s strain more obvious, so the slope which formed because of the accumulation bocly excavation still need to support powerfully.
