INFLUENCE OF THE LOAD LEVEL, CHANGE IN THE FREATIC LEVEL AND HEIGHT OF THE COHESIVE STRATUM ON THE CONSOLIDATION SETTLEMENTS IN A SYMMETRICAL BUILDING

The research evaluates the consolidation liquidations generated by a four quadrant building, where each one of the foot types is studied changing some of these parameters, to know which of these three aspects is the one that more influences in the consolidation liquidation in buildings of three levels, The methodology includes change the amount of levels that affect the load and dimensions of the footing, analysis of variables and influence of the change of phreatic level in another of the footing and finally the settlement is evaluated with the change of height of the soft stratum, that will be the consolidated stratum. It is concluded that the analysis of the variability of the settlements caused by the change of factors load levels, dimensions of the footings, variability of the phreatic level and change in the height of the cohesive stratum, where the consolidation will be presented.


I. INTRODUCTION
The accelerated expansion of cities and urban areas results in an increase in sustainable buildings, transport and environmental services, which correctly respond to all the needs of a society [12].

Studies carried out
For the concentric shoe, the changes in settlement are calculated as the number of floors to be studied changes, which affects the base of the shoe and finally the primary displacement or settlement.
In the corner footing, the change in footing settlement is made in relation to the location of the water table.
And in the dividing footing, the behavior of settlement variation according to the height of the cohesive stratum is studied.

III. Results and Discussion
The results of the stress calculation, taking  Then, the widths of the footings were determined with the equation 1 (1) With a Q admissible value of 120kN you get: The consolidation test is carried out and the following data are obtained:

Centre Footing
Thus, for the first analysis, that of the concentric shoe, the settlements are calculated according to the change of floors and therefore the width of the footings. Finally, the results of the analysis are:

Corner footing
The corner footing is worked under the following soil conditions

Dividing flooting
The conditions of the soil layers for the median shoe were as follows: Then, due to the change in the height of the stratum, the behavior of the consolidation settlement can be observed.  where the consolidation will be presented.
In the first study, it was observed that the increase in settlement increases by 34% when the floor level is increased from 3 to 6, and a footing width of 4. 2m to 6m, and a similar increase is observed when 3 more floors are increased, that is, three times the amount of initial floors. Later, when a level of 12 floors or more is reached, the settlement no longer has considerable variability, this is due to the fact that most of the air or water that exists between the pores has been drained, where the soil could fail due to cutting and would cause subsidence.
In the second study, the relationship between the variability of the water table, that is, the depth at which the groundwater is found, in relation · 2 9 9 · equilibrium of consolidation; however, this is very counterproductive in terms of long-term effects.
