Description
Technical field
The present invention relates to the measurement mechanism of the physico-mechanical properties of the water-bed soil body, specifically the soil in-situ hole is pressed and is influenced depth monitor under the wave action.
Background technology
The wave period load action produce excess pore water pressure (being called for short the hole presses) in the soil body, but accumulation hole pressure is covered with efficacy above on the soil body, and unstability will take place the soil body, will produce the geologic hazard phenomenon, and marine engineering normal construction and operation are worked the mischief.Existing static sounding and pore pressure gauge equipment, monitoring is pressed in the hole that is widely used in marine soil property classification, layering and dam body, but only limit to the hole, top layer for seafloor soil and press observation, and can not layering observe, therefore also can't detect the degree of depth that influences of different big rips; In addition, also lack the mensuration of on-the-spot soil body resistance parameter, this parameter is to determine an important indicator of soil corrosivity, and is closely related with the mission life of seabed engineering structures (as subsea pipeline).
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide under a kind of wave action of monitoring the excess pore water pressure that wave different depth place in the soil body produces the soil in-situ hole to press and influence depth monitor.
Another object of the present invention is when monitoring soil body endoporus is pressed, can also monitor the degree of depth that influences of the big or small wave of difference, and the resistivity of testing the different depth soil body simultaneously is to determine the corrosivity of soil to pipeline, structure base.
On the basis of prior art, this device includes measuring staff and the corresponding automated data acquisition device that the pore water pressure sensor of static point resistance sensor, side friction sensor and the postpone thereof of sleeve and leading section is formed, and it is characterized in that it also comprises with the alternate a plurality of pore water pressure sensors that are laid on the long measuring staff of joint; On above-mentioned corresponding joint, also laid soil body resistivity sensor, so that the resistivity of the while and the in-site measurement soil body.
