The invention discloses a measurement
system and method for the stress of the surrounding rock of a hipparion
red soil tunnel under the influence of crack water. The measurement
system for the stress of the surrounding rock of the hipparion
red soil tunnel under the influence of the crack water comprises a
signal amplifier, a
data collector, an upper computer, a power supply and eight sensor groups; the sensor groups are connected with the
data collector by the
signal amplifier, and the
data collector is connected with the upper computer; the eight sensor groups are respectively installed at the arch crown of the monitoring section of a hipparion
red soil tunnel, both sides of the arch
waist of the monitoring section of the hipparion red soil tunnel, both sides of the side wall of the monitoring section of the hipparion red soil tunnel, both sides of the arch foot of the monitoring section of the hipparion red soil tunnel and the position of the inverted arch of the monitoring section of the hipparion red soil tunnel; and the data of soil pressure and
water pressure are collected in real time by the sensor groups, the collected data are transmitted to the data collector by the
signal amplifier, the data are collected by the data collector according to a certain frequency and are also transmitted to the upper computer, and the received data are processed by the upper computer. According to the measurement
system and the method for the stress of the surrounding rock of the hipparion red soil tunnel under the influence of the crack water, the influence degree of the pressure of pore water to the total stress of the surrounding rock in the construction process of the hipparion red soil tunnel can be quickly, continuously and accurately measured, the problem existing in the construction process is fed back in time, and a
construction design scheme is regulated in real time.
