Description

The method of vacuum pre-pressed joint electric osmose test unit and the test of vacuum pre-pressed joint electric osmose
Technical field
The present invention relates to a kind of vacuum pre-pressed joint electric osmose test dress.The invention still further relates to the method adopting above-mentioned vacuum pre-pressed joint electric osmose test unit to carry out the test of vacuum pre-pressed joint electric osmose.
Background technology
At present, coastal cities are for alleviating the nervous contradiction of land used, and a large amount of soil need be formed by reclaiming land around sea.Reclaiming land around sea barged-in fill used generally adopts the dredging silt in basin and navigation channel, and form land-based area place through waterpower hydraulic reclamation, water percentage is up to more than 80%, and the place of hydraulic reclamation even can reach about 200% recently.In addition, due to waterpower sorting reason, soft soil foundation upper soil horizon particle is superfine, based on glutinous grain and micelle, connects very weak between particle, and not yet form the soil skeleton structure with intensity, soil particle is strong with water flow.Soft clay has many disadvantageous engineering propertiess such as high-moisture, high-compressibility, high thixotropic, low shearing strength.High-compressibility can cause ground to have sizable sedimentation and differential settlement; Low-permeability makes the duration of sedimentation very long, likely affects the normal use of buildings; Low-intensity makes foundation bearing capacity and stability often can not engineering demands.Therefore, reinforce this type of super soft foundation how effectively, fast, economically and then become a technical barrier that must solve.
Vacuum method is taught by imperial family of Sweden geological institute Jie Erman and is proposed in nineteen fifty-two, and compare the soft-soil foundation treatment methods such as natural drying method, preloading, vacuum method all has obvious advantage on required time and treatment effect.In recent years, the research work relevant to vacuum preloading gets more and more, and the application of vacuum preloading in Practical Project also constantly increases, and developing prospect is wide.And when vacuum preloading process infiltration coefficient be 10 -8cm/s is even close to 10 -9just show limitation during the low-permeability soft clay of cm/s, treatment effect is often limited by the size of vacuum tightness in the degree of depth of the soil body and soil.In order to reach the effect of the better process soil body, follow-uply develop again the new technology of much combining with additive method, as vacuum-surcharge preloading method, vacuum pre-pressed joint heavy-tamping method, vacuum pre-pressed joint electro-osmosis method.Because vacuum preloading has similar reinforcement mechanism with electric osmose to the soil body, and electro-osmosis method is not by the impact of soil particle size, and two kinds of methods all can not make the soil body produce shear failure in loading procedure.When vacuum-electric osmose synergy: when early stage water content of soil is larger, just can discharge most free water in soil fast by means of only vacuum method, but along with the reduction of water cut, vacuum preloading treatment effect reduces; When the later stage, water content of soil was less, just can reduce the water cut in the soil body further with the precompressed of electric osmose combined vacuum.Just the limitation of traditional foundation treatment mode can be changed by the use in conjunction of vacuum preloading and electric osmose, reach the object of effective soil mass consolidation, reduce time and the cost of basement process to the full extent, so vacuum preloading-electro-osmosis method just to become in Soft Ground comparatively effectively and one of the method for future (having good application prospect).
Though vacuum preloading-electro-osmosis method has obvious advantage when soft soil foundation, increasing expert has also carried out this and studies and achieve good achievement, but still has Railway Project not yet to solve: in vacuum preloading process, the Changing Pattern of drain bar bending is failed to understand, the transfer law of native Pore Pressure and vacuum tightness is failed to understand, the conformability of vacuum system and electric osmose system is not high.Carrying out model test in indoor is the research cooperative programs of vacuum-electric osmose and the best mode of interaction mechanism, is also the prerequisite and the important step that vacuum-electric osmose associating foundation treatment mode are generalized to large-scale application in Practical Project.Though existing model test apparatus energy possesses good fitting ground is at lab simulation vacuum preloading, cannot observe the situation of change of drain bar, in soil, the burial place of sensor can not accurately control.In addition, the derivation of a large amount of sensor line also can increase the weight of the gas leakage on diaphragm seal surface, weakens its sealing, makes soil body vacuum tightness can not reach expection requirement.
