Method for measuring settlement deformation by utilizing inclinometer and angle-adjustable converter

Abstract

The invention belongs to the technical field of measurement for the settlement deformation of high fills, and aims to provide a method applied to a V-shaped route in a single-free face high fill foundation horizontal plane and used for measuring the settlement deformation in a way of driving an inclinometer to move through an angle-adjustable converter by utilizing a measuring line. According to the technical scheme, by the method for measuring the settlement deformation by utilizing the inclinometer and the angle-adjustable converter, the inclinometer on the measuring line moves in settlement pipes through the angle-adjustable converter to measure the settlement deformation of a single-free face high fill foundation. The measurement method comprises the following steps of 1, selecting a reference point and an observation section; 2, burying the settlement pipes and the angle-adjustable converter; 3, observing and recording initial data; 4, measuring the elevations of section outlet points after settlement; 5, performing zero setting on the inclinometer; 6, measuring the settlement deformation; 7, organizing and analyzing data. The method is mainly used for measuring the settlement deformation of the single-free face high fill foundation.

Description

technical field [0001] The present invention uses an inclinometer to measure settlement deformation through an angle-adjustable converter, which belongs to the technical field of high fill settlement deformation measurement, and in particular relates to the measurement of settlement deformation of a V-shaped line in the horizontal plane of a high fill foundation with a single empty surface . Background technique [0002] With the expansion of our country's capital construction scale, the construction land is becoming more and more scarce, and the requirements for land use are getting higher and higher. In recent years, in order to avoid competing for land with fertile land, many cities have proposed the development strategy of "industry out of the city and projects up the mountain". Deep digging and high filling. At present, the filling body of high fill foundation adopts layered backfilling, layered compaction or tamping. It is particularly important to control the settl...

Problems solved by technology

[0003] Most of the existing methods of measuring settlement deformation use the vertical direction to measure discrete hole positions. This method not only causes inconvenience to the construction in the process of reservation and protection of settlement holes, but also the measured data is only a few A discrete hole position cannot fully represent the settlement value of a certain section

[0004] However, the current method of using the inclinometer to observe the linear settlement along the horizontal direction can only be applied to high filling projects with double empty faces.

Obviously, the existing measurement methods for high fill projects with only one free face are very limited
