Pełny tekst źródłaThe tests used were: total porosity as calculated from densimeter readings and from soil cores; structural porosity; water desorption characteristics; and soil profile examination. These tests were performed in three layers of 20 cm and evaluation was based on their practicality and their ability to differentiate between treatments and to correlate with corn yield.
The results confirm that total porosity is a poor indicator of compaction in the subsoil. In soil profile assessments, ped descriptions were preferable to examination of pores. Water content and saturation deficit at $-$4.0 and $-$100 kPa were the best indicators of treatments and plant response.

Pełny tekst źródłaA numerical procedure, coded into a numerical code (MISS3D-EqL), is developed to accommodate for the effects of the nonlinear soil behavior on the soil-structure interaction (SSI) using an equivalent linear approach. Equivalent linear behavior is assumed for the soil, while the response of the structure to the ground shaking and its effects on the soil are properly taken into account using the substructure method. The proposed procedure is validated against other numerical software and experimental means, such as shaking table and centrifuge tests. The effects of the equivalent linear soil behavior on the soil-structure system response are clearly demonstrated by analyses of representative case studies. A recursive analysis of typical soil profiles and infrastructures is performed to reveal the further softening of the system and the increased energy dissipation, compared to the linear case, due to the equivalent linear soil behavior. Special emphasis is given to the estimation of the foundation dynamic impedance functions. Dynamic stiffness and radiation dashpot coefficients are estimated for typical footings resting on typical soil profiles with equivalent linear behavior. The effects of the nonlinear soil behavior on the dynamic coefficient are shown compared to the linear elastic case. The dynamic stiffness coefficient decreases with increasing input acceleration amplitude, with decreasing soil shear wave velocity and with decreasing soil shear modulus, while it depends on the frequency content of the earthquake. The radiation dashpot coefficient is unaffected by the nonlinear soil behavior for most practical applications

Pełny tekst źródłaThe present work addresses a computational methodology to solve dynamic problems coupling time and Laplace domain discretizations within a domain decomposition approach. In particular, the proposed methodology aims at meeting the industrial need of performing more accurate seismic risk assessments by accounting for three-dimensional dynamic soil-structure interaction (DSSI) in nonlinear analysis. Two subdomains are considered in this problem. On the one hand, the linear and unbounded domain of soil which is modelled by an impedance operator computed in the Laplace domain using a Boundary Element (BE) method; and, on the other hand, the superstructure which refers not only to the structure and its foundations but also to a region of soil that possibly exhibits nonlinear behaviour. The latter subdomain is formulated in the time domain and discretized using a Finite Element (FE) method. In this framework, the DSSI forces are expressed as a time convolution integral whose kernel is the inverse Laplace transform of the soil impedance matrix. In order to evaluate this convolution in the time domain by means of the soil impedance matrix (available in the Laplace domain), a Convolution Quadrature-based approach called the Hybrid Laplace-Time domain Approach (HLTA), is thus introduced. Its numerical stability when coupled to Newmark time integration schemes is subsequently investigated through several numerical examples of DSSI applications in linear and nonlinear analyses. The HLTA is finally tested on a more complex numerical model, closer to that of an industrial seismic application, and good results are obtained when compared to the reference solutions

Pełny tekst źródłaDespite the significant progress in simple engineering design of surface footing with considering the soil-structure interaction (SSI), there is still a need of the same procedure for the pile group foundation. The main approach to solve this strongly coupled problem is the use of full numerical models, taking into account the soil and the piles with equal rigor. This is however a computationally very demanding approach, in particular for large numbers of piles. The originality of this thesis is using an advanced numerical method with coupling the existing software MISS3D based on boundary element (BE), green's function for the stratified infinite visco-elastic soil and the matlab toolbox SDT based on finite element (FE) method to modeling the foundation and the superstructure. After the validation of this numerical approach with the other numerical results published in the literature, the leading parameters affecting the impedance and the kinematic interaction have been identified. Simple formulations have then been derived for the dynamic stiffness matrices of pile groups foundation subjected to horizontal and rocking dynamic loads for both floating piles in homogeneous half-space and end-bearing piles. These formulations were found using a large data base of impedance matrix computed by numerical FE-BE model. These simple approaches have been validated in a practical case. A modified spectral response is then proposed with considering the soil-structure interaction effect
