Abstract

The invention discloses a building anti-floating water level value taking method suitable for a confined aquifer field. The invention can effectively avoid the defects obtained according to the traditional method and avoid the occurrence of anti-floating failure accidents.

Description

A kind of building hydrostatic water table obtaining value method suitable for artesian aquifer place
Technical field
It is more particularly to a kind of to be directed to artesian aquifer place class the invention belongs to building structure anti-floating field of engineering technology The hydrostatic water table obtaining value method of type.
Background technology
Underground hydrostatic water table is the core of Anti-floating design, it is determined that reasonable and safe hydrostatic water table is key in survey Link.Existing specification, handbook, document are unified for the determination of anti-uplift ground water level, specific method or formula, greatly It is to survey peak level by prospecting that many hydrostatic water tables, which are provided, and nearly 3~5 years peak levels or highest water level on records are even outdoorly Level ground absolute altitude determines, but in artesian aquifer place, after top water proof stratum has been exposed on underground structure or basis, anti-floating water Position is higher than level of ground water, therefore empirically value frequently results in unreasonable or even wrong value result, triggers anti-floats request to lose The accidents such as effect.
The content of the invention
The purpose of the present invention is to be directed to for the not enough of the existing determination method for anti-uplift ground water level there is provided one kind The hydrostatic water table obtaining value method of artesian aquifer Site Type, so as to avoid traditional empirically value from obtaining unreasonable or mistake By mistake value result and trigger anti-floats request failure etc. accident.
The technical scheme is that:
By observing artesian water water level elevation, the outcrop of spring elevation of hole measurement, drafting place, place SEA LEVEL VARIATION are linear Graph of a relation, place hydrostatic water table excursion is determined by SEA LEVEL VARIATION linear graph, and overall underground structure is determined anti-by high level Swim position, hydrostatic water table is determined by high level between built-up area under piecewise.
Further, comprise the following steps:
1) analysis formation structure and Geologic Structure Feature;
2) analyze place hydrogeological characteristics, artesian water refer to underground water full of up and down between two water barriers can lava contain In water layer and the underground water with certain head pressure, the solution cavity, molten that underground water is mainly developed by interlayer structure face, concordant Split and drained from high potential energy area along to oblique core portion to low-potential energy area, contact band with water barrier in soluble water-bearing layer and be often accompanied by ascending-type Outcrop of spring shows;
3) by observing the water level elevation, bottom artesian water water level elevation, outcrop of spring of hole measurement top phreatic aquifer Elevation, draws place, place SEA LEVEL VARIATION linear relationship chart;
4) place hydrostatic water table excursion is determined by SEA LEVEL VARIATION linear graph, overall underground structure is determined by high level Hydrostatic water table;Under piecewise hydrostatic water table is determined between built-up area by high level.
The present invention is directed to artesian aquifer place there is provided reasonable, the reliable hydrostatic water table computational methods of one kind, due to field There is artesian head in ground, after top water proof stratum has been exposed on underground structure or basis, underground flood peak may eminence ground, because The drawbacks of this is prevented effectively from according to obtained by conventional method, it is to avoid the generation of anti-floating failure accidents.
Brief description of the drawings
Fig. 1 is that underground structure basis is located at artesian aquifer hydrostatic water table signal log sheet.In figure:1. karst contains The rising water of 2. water barrier of water layer 3. and exposure elevation 4. drill and the first paragraph place of 5. phreatic line of water level elevation 6. and Hydrostatic water table h1
Embodiment
The invention will be further described with reference to the accompanying drawings and examples, but not as any limitation of the invention.
As shown in figure 1, the present invention is by observing the artesian water water level elevation of hole measurement, outcrop of spring elevation, drawing field Area, place SEA LEVEL VARIATION linear relationship chart, place hydrostatic water table excursion is determined by SEA LEVEL VARIATION linear graph, integrally under Building determines that high level is determined between built-up area under hydrostatic water table, piecewise by high level.
Specifically, the step of determining the building anti-uplift ground water level in artesian aquifer place is as follows:
1. formation structure and Geologic Structure Feature are analyzed, pressure-bearing type aquifer water-bearing stratum place refers to be up and down with one It is the preferably soluble limestone of the property of water-bearing, dolomite distribution of strata area to determine the water proof or weak permeable stratum of thickness, middle part, and pressure-bearing contains Water layer distributed area is mostly synclinal structure, such as down fold paddy or synclinal basin;
2. analyze place hydrogeological characteristics, artesian water refer to underground water full of up and down between two water barriers can lava contain In water layer and the underground water with certain head pressure, the solution cavity, molten that underground water is mainly developed by interlayer structure face, concordant Split and drained from high potential energy area along to oblique core portion to low-potential energy area, contact band with water barrier in soluble water-bearing layer and be often accompanied by ascending-type Outcrop of spring shows;
3. by observing the water level elevation, bottom artesian water water level elevation, outcrop of spring of hole measurement top phreatic aquifer Elevation, draws place, place SEA LEVEL VARIATION linear relationship chart;
4. place hydrostatic water table excursion is determined by SEA LEVEL VARIATION linear graph, overall underground structure is determined by high level Hydrostatic water table;High level is determined between built-up area under piecewise.
The artesian water water level elevation by observing hole measurement, the outcrop of spring obtained according to technical scheme is high Journey, draws place, place SEA LEVEL VARIATION linear relationship chart, as shown in Figure 1.
In figure:Building basis be placed in above and below in karst aquifer between water barrier, after top water barrier is exposed, place Phreatic line can be according to drilling water level elevation H1, karst source exposure elevation H2、H3It is determined, determines that method is as follows:Brill Hole water level elevation H1, karst source exposure elevation H2、H3Project on section, the phreatic line for obtaining place is connected with straight line. Sloping area segmentation provides the hydrostatic water table in place, each section of this section of hydrostatic water table area level of ground water peak, such as first paragraph Take h1, second segment takes h2
Certainly, it is the concrete application example of the present invention above, the present invention also has other embodiments, all using equivalent Replacement or the technical scheme of equivalent transformation formation, all fall within protection domain of the presently claimed invention.
