The invention discloses a train tunnel periphery liquefiable soil body desaturation treatment system and a construction method.The train tunnel periphery liquefiable soil body desaturation treatment system comprises a tunnel and a train, the tunnel comprises an electrolysis section tunnel and a non-electrolysis section tunnel, the electrolysis section tunnel and the non-electrolysis section tunnel are arranged at intervals, a passive coil is embedded in the electrolysis section tunnel, electrodes are arranged at the two ends of the passive coil, and the electrodes are connected with the electrolysis section tunnel. A monitor is mounted on the passive coil and is connected with the control system; the train comprises a plurality of carriages, a carriage connecting part is arranged between every two adjacent carriages, and a driving coil is arranged on the outermost side of each carriage connecting part. Under the condition that the soil body is not disturbed, the soil body on the periphery of the tunnel is subjected to desaturation, and the liquefaction resistance strength of the soil body can be remarkably improved; a system for monitoring and adjusting the soil saturation in real time is arranged, the soil state can be transmitted to a subway control system in time, power consumption can be reduced when the soil state is good, and saturation reduction treatment can be conducted in time when the soil state is poor.
本发明公开了一种列车隧道外围可液化土体减饱和处理系统及施工方法,包括隧道和列车,所述隧道包括电解段隧道和非电解段隧道,电解段隧道和非电解段隧道间隔布置,其中,电解段隧道内嵌有被动线圈,所述被动线圈两端设有电极,所述被动线圈上安装有监测器,所述监测器与控制系统连接;所述列车包括若干车厢,相邻车厢之间设有车厢连接处,所述车厢连接处的最外侧设有主动线圈。本发明能够在不扰动土体的情况下,对隧道外围土体进行减饱和,能够显著提高土体的抗液化强度;具有对土体饱和度实时监测与调整的系统,能够及时将土体状态传递给地铁控制系统,土体状态良好时,可减少电能消耗,土体状态不良时及时进行减饱和处理。
