Abstract
The soil mechanic laboratory results help in accurate soil foundation design and enhancement failure mitigation. The mixing soil design has been used in many geotechnical engineering for soil improvement. In this paper, several types of soil foundations have been made from mixed soil. The bearing capacity of soil foundations by using mixed soil parameters and change footing dimensions have been calculated. 180 footings, placed on 15 soil foundation types have been designed. It is assumed the underground water has not effect to bearing capacity of soil foundation. The results of numerical analysis and mixed soils technique have been combined. The numerical analysis has supported mixed soil design, and introduced an appropriate result for soil foundation design. The effects of mixed soil on depth and width of footing have been compared. The mixed soil design influenced numerical analysis result, and economically, soil foundation design helps to select the appropriate dimensions of footings. The result of numerical analysis supports geotechnical and structural engineering codes, predicts structural stability with different age, natural hazard and prevention as well as it is useful in understanding safe bearing capacity of soil foundation behavior.
Highlights
T he mathematical modeling and numerical simulation have been used to understand tsunami behavior, and a mitigation technique has been proposed, based on bearing capacity of soil concept [1]
The numerically wave theory concept has been applied in analyzing confined sandy dense columns, and the study indicated that the dense zone improves soil foundation bearing capacity [4]
To evaluate the safe bearing capacity of soil foundation and select appropriate dimensions of concrete foundation, when soil foundation is constructed from mixed soil, a numerical analysis has been made; ithas been attempted to appropriately improve stability of structures, to optimize application of mixed soil in soil foundation design, and to achieve realistic simulation of soil foundation design
Summary
T he mathematical modeling and numerical simulation have been used to understand tsunami behavior, and a mitigation technique has been proposed, based on bearing capacity of soil concept [1]. A new method for calculation of liquefaction force numerically is suggested It is applicable for improving geotechnical and structure codes and for the reanalysis of structure and stability of previously constructed buildings [5]. The ZEL method is employed to consider the stress level dependency of soil strength in the bearing capacity computation and load-displacement behavior of foundations, with a computer code was developed in MATLAB to solve. To evaluate the safe bearing capacity of soil foundation and select appropriate dimensions of concrete foundation, when soil foundation is constructed from mixed soil, a numerical analysis has been made; ithas been attempted to appropriately improve stability of structures, to optimize application of mixed soil in soil foundation design, and to achieve realistic simulation of soil foundation design. Nc and Nγ are the general bearing capacity factors and depend upon 1) depth of footing 2) shape of footing 3) Φ; they have been used from suggestion by the Terzaghi calculation method [11]
