Fig. 1 shows the schematic diagram according to the monitoring method of the subgrade settlement of an embodiment of present specification.An embodiment of the monitoring method of reference subgrade settlement shown in Figure 1:
Along railway line, every a segment distance monitoring node (settlement monitor namely is installed) is set.As shown in Figure 1, all monitor pipeline communications consist of linker.Because the atmospheric pressure in some areas can not have very big difference, so the same liquid in the linker is when flowing, and the direct liquid level that contacts with atmosphere always keeps sustained height in each container.If somewhere ground generation sedimentation, the distance D meeting respective change in the monitor between measuring sonde and the liquid level; Abundant when the monitoring node, namely monitoring range enough greatly the time, can think that non-uniform settling has occured on this ground, and the D value by each monitor of analysis-by-synthesis measures can obtain its settling amount, and by wireless network each D value is transferred to monitoring center.
Fig. 2 shows the schematic diagram according to the monitoring method of the subgrade settlement of another embodiment of present specification.Another embodiment of the monitoring method of reference subgrade settlement shown in Figure 2:
Measurement accuracy D value is to guarantee reliable, the stable precondition of Monitoring Data.Ultrasonic ranging method is record emission sound wave and the mistiming Δ t that receives between the echoed signal, the distance with barrier that obtains popping one's head in of the product by calculating acoustic wave propagation velocity V and Δ t.Yet, stable and accurately velocity of sound V be the necessary condition that guarantees measuring accuracy, in actual applications, the various factorss such as the temperature of propagation medium, pressure, humidity, density all can have a direct impact velocity of sound V.
The present embodiment has overcome the fluctuation of speed V to the impact of measuring accuracy by the relative type motor measuring method.As shown in Figure 2, the receiving transducer of a transmitting probe (purpose is for the conditions such as the frequency that guarantees to transmit, amplitude are all identical, reduces error) and two certain altitudes that mutually stagger.The inner space of monitor is less, can think that propagation medium is uniformly, so speed V is consistent.Can get thus:
2D+H

2) （3）
Can be found out by (3) formula, the D value is measured with velocity of sound V irrelevant.
Can draw from above analysis, another embodiment of the monitoring method of subgrade settlement is, described detector comprises a transmitting probe and two receiving transducers, described two receiving transducers are not at sustained height, and in the vertical direction staggers mutually, and make mounting distance between two receiving transducers and the transmitting probe, equal separately hyperacoustic actual propagation distance.
On basis embodiment illustrated in fig. 2, be further analyzed, as shown in Figure 3, be ultrasonic probe and surface level off plumb situation.
Only when ultrasonic probe during fully perpendicular to surface level, sound wave just equals mounting distance at transmitting probe to the propagation distance between the receiving transducer.Complicated field condition is so that monitor hardly may horizontal positioned, such as the H among Fig. 3 yet in actual applications,
1', H
2' be the Acoustic Wave Propagation distance, H
