During the shield advancing process, the advancing speed is very slow, and the shield advancing process can be considered as uniform motion, so the acceleration is 0, namely a is 0. Therefore, the method comprises the following steps: f ═ Ff+FpNamely, the total thrust of the shield tunneling machine is equal to the sum of the resistance of the soil body in front of the cutterhead during tunneling and the backward resistance of the shield body, and the mechanical schematic diagram of the tunneling process is shown in fig. 2.
Further, the backward resistance F generated in the tunneling process of the shield tunneling machinefThe method comprises the following steps: frictional resistance F generated by shield body and surrounding soil body1Resistance F generated by friction between rear half part of shield tunneling machine and segment2Resistance F generated when the supporting vehicle behind the shield machine transports the muck3Frictional resistance F generated by self gravity of shield machine4I.e. Ff=F1+F2+F3+F4Wherein F is1、F2、F3、F4The specific calculation method is as follows.
(1) Frictional resistance F generated by shield body and surrounding soil body1
The self weight of the soil body generates pressure on the surface of the shield, and further generates frictional resistance in the tunneling process of the shield tunneling machine, wherein the frictional resistance comprises vertical soil pressure and lateral soil pressure. As the excavation surface of the shield machine is a circular section, the vertical soil pressure and the lateral soil pressure are considered to be symmetrical up and down and left and right. Therefore, in the invention, the vertical and lateral soil pressures are calculated within the range of 0-pi/2, and then multiplied by 4 to obtain the total pressure of the shield surface. The vertical soil pressure acting on the shield body is as follows:in the formula, PVThe vertical soil pressure is adopted, gamma is the soil mass volume weight, g is the gravity acceleration, H is the buried depth of the shield tunneling machine, and D is the diameter of the shield tunneling machine. The lateral soil pressure acting on the shield body is as follows:in the formula, PHIs lateral soil pressure, k0Is the lateral pressure coefficient of soil body. Thus, the shield surface is subjected to a total pressure of:therefore, the frictional resistance between the shield and the surrounding soil body can be obtained as follows:in the formula, mu1For the friction coefficient between the shield body and the surrounding soil body, other parameters have the same meanings as those in the above formula, and are not repeated herein.

The pressure of the soil body at the opening part of the cutter head acting on the pressure-bearing partition plate is as follows: fp2=πD2p0c/4, in the formula, p0The soil pressure in the sealed cabin can be monitored in real time by a pressure sensor in the sealed cabin. Therefore, the resistance of the soil body in front of the front face of the cutter head when the shield tunneling machine tunnels is as follows: fp=Fp1+Fp2=πD2k0hγ(1-c)/4+πD2p0c/4。
