Embodiment Construction

[0032] Such as Figure 1-2 As shown, a tunnel full-longitudinal surface settlement monitoring system based on a static level includes a static level unit 10 at the starting point, a static level unit 20 at the end point, and m sets of middle Static level unit 11; wherein the starting point static level unit 10 and the end point static level unit 20 are respectively distributed laterally along the tunnel cross-section on the upper surface of the tunnel entrance and exit to be tested, and the middle static level unit 11 is longitudinally arranged along the tunnel length direction The ground surface above the tunnel to be tested.

[0033] Starting point static level unit 10 comprises p only static level measuring point 4 and No. 1 water tank 1, No. 1 static level datum point 2 communicated by connecting pipe 3, and described No. 1 water tank 1 and No. 1 static level datum Point 2 is set on the same concrete base 6 . The terminal static level unit 20 includes q static level meas...

Abstract

The invention discloses a tunnel full-longitudinal ground surface settlement monitoring system and method based on static force level gauges. The monitoring system comprises a starting point static force level gauge unit, an end point static force level gauge unit and m sets of middle static force level gauge units which are sequentially arranged from a measurement starting point to a processing end point in a cascading mode. Wherein the starting point static force level gauge unit and the end point static force level gauge unit are transversely arranged on the tunnel top surface of a tunnel entrance and a tunnel exit respectively along the section of the tunnel, and the middle static force level gauge units are longitudinally arranged on the tunnel top surface along the length direction of the tunnel; the relative settlement amount between the measuring points is obtained through monitoring, the relative settlement amount and the known settlement amount are added, the absolute settlement amount of each measuring point is obtained, and the system and the method have the advantages of being easy and convenient to operate, high in monitoring precision, capable of achieving automatic monitoring of ground surface full-longitudinal settlement and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of tunnel engineering monitoring and is used for automatic monitoring of tunnel surface settlement, in particular to a tunnel full longitudinal surface settlement monitoring method based on a static level. Background technique [0002] The surface settlement monitoring of the tunnel roof caused by tunnel construction is a must-measure item for monitoring and measurement, which can effectively prevent problems such as cracking and subsidence of the overburden of the tunnel. At the same time, the monitoring and research on the longitudinal settlement of the tunnel roof surface can provide data support for the definition of tunnel depth, determine the range of loose loads and plastic circles, and optimize the length of the tunnel entrance section and support measures. There are few studies and measured data on the longitudinal settlement law of the tunnel roof surface. [0003] Due to its high precision, small size, eas...
