The invention discloses an adjustable settlement measurement device based on multiple resistance type pore pressure meters and a measurement method. The device comprises a vertical sealed pipe, a standard resistance type pore pressure meter, a wide-range resistance type pore pressure meter, a small-range resistance type pore pressure meter, an electronic control tee joint and a voltage meter. The standard resistance type pore pressure meter buried in a non-settlement-influence area is connected with the vertical sealed pipe through a plastic hose, the wide-range resistance type pore pressure meter and the small-range resistance type pore pressure meter which are buried in a settlement influence area side by side are connected with the vertical sealed pipe through plastic hoses, and a closed system full of liquid is formed. The measurement device and the measurement method are based on the principle that soil settlement is converted into measurement of pressure change of liquid in the closed system, measurement precision is high, operation is easy and convenient, and the measurement device and the measurement method are suitable for settlement measurement under different kinds of soil deformation. Besides, normal construction and use of projects are not affected, and personal safety of detection personnel is guaranteed.
Description
technical field [0001] The patent of the present invention relates to the technical field of soft soil foundation settlement, specifically an adjustable settlement measurement device and measurement method based on a multi-resistance pore piezometer. Background technique [0002] Under the load of the building, the foundation will settle with the dissipation of excess pore water pressure and the increase of effective stress. If foundation settlement occurs, especially if uneven settlement occurs, once it exceeds the allowable range of the building on the foundation, it will affect the normal use of the building at least, and even lead to cracking and tilting of the building, subsidence of the roadbed, and collapse of the embankment. The settlement has a significant impact on the safety of buildings, so the problem of foundation settlement is of great concern to engineers. In actual engineering, on-site measurement is required to clarify the actual settlement in the project. ...
