“…Choosing the same parameters listed above, the depth of foundation is 4m, plane sizes is× b, then the results show in Table 3: From the table above, when the plane sizes of foundation are increase, the convergence tendency of main stress is obvious; when the plane sizes is more than 7.5 ×16m, the main stress is barely decreasing, it means that the main stress is almost converged, so we choose the plane sizes of foundation as 7.5× 16 m [4].…”

The thesis,on the basis of summarizing the present study and appliance at abroad and home, integrates the present test standard with the special environment of pavement, to discuss systemically the design theory of pavement for supplying the reliable theory for the design. Then, ANSYS is used to make the stimulation calculation of SFRC, and to analyze the result, then as well as to put forward the slab length about 16m; Finally, to test the major property of SFRC verifies the favorable property of Steel fiber reinforced concrete, and connecting the practical conditions of pavement, by the structure design, verifies the feasibility of applied to supply a better way for designing the pavement.

“…is is because the maximum tensile stress is related to the bending sti ness of the concrete slab. An increase in the bending sti ness decreases the maximum tensile stress [20,33]. Moreover, the bending sti ness of the concrete slab is proportional to the third power of the slab thickness.…”

“…Vishwakarma and Ingle presented that most of the concrete pavements have a thickness below 35 cm [33]. ey have also concluded that the critical stresses of the concrete slab for L/W ratio 1.25 or below are almost the same [20]. In this study, to optimize structural parameters of regional airport JCP, given the combined e ect of large temperature gradient and aircraft loads, 144 numerical models were developed, as shown in Table 5.…”

Daily changing temperature causes significant thermal stress in concrete pavement. Tensile stress obtained can exceed flexural tensile strength when the concrete slabs are subjected to large temperature gradient and traffic loads, resulting in pavement damages. In this paper, maximum tensile stresses in concrete slabs with different slab sizes, thicknesses, and length to width (L/W) ratios were investigated by using the finite element (FE) method. The important parameters in the design of concrete pavement are the flexural tensile strength and the fatigue limit. By analyzing the comparison results between the maximum tensile stress and the fatigue limit, the optimum slab size and the critical thickness were determined. The results indicate that the maximum tensile stress obtained is higher for larger slab size with thin thickness. Furthermore, to reduce cutting work and the amount of dowel bars, the optimum slab sizes of the regional airport concrete pavement are recommended as 4 m × 4 m to 6 m × 6 m. The critical thicknesses of 4 m × 4 m slab and 6 m × 6 m slab are determined as 28.2 cm and 34.7 cm, respectively, based on the most unfavorable coupling between positive and negative temperature gradients and the Boeing 737–800 aircraft load. Moreover, the maximum tensile stress increases as the L/W ratio increases. When the slab length is less than 6 m, it is better to use square slab in airport jointed concrete pavement (JCP).

“…Lee & Han studied the size effect of the foundation, and they found that the bearing capacity coefficient decreased with increase of the foundation width [22]. Vishwakarma & Ingle found that the critical stress was higher for the smaller concrete pavement panel sizes [23]. Mehrjardi & Khazaei determined that the size effect of the reinforced soil played an important role in the response of the reinforced foundation [24].…”

To determine the energy attenuation and energy reflection coefficients in layered foundation is the key factor to reveal the dynamic response characteristics of the high-speed railway foundation. Based on the foundation test model under the dynamic loading of the high-speed railway, the energy attenuation and energy reflection coefficients were introduced and the attenuation formulas of the vibration acceleration in the layered foundation were deduced. Five scale models of 1:1, 1:2, 1:5, 1:10 and 1:20 are established respectively by using Abaqus technique. The energy attenuation mechanism and interfacial energy reflection characteristics in the layered foundation were analyzed. Results show that it is appropriate to use vibration acceleration to characterize the propagation rule of the energy attenuation in the layered foundation. The size effect equations of the energy attenuation and energy reflection coefficients in the layered foundation are deduced and the size effect of the energy attenuation is revealed. Based on the nonlinear relationships among the energy attenuation coefficient, the model scale, the loading amplitude and the vibration frequency, the energy attenuation equation of the scale test model is constructed. The reliability of the theoretical and simulation results is verified by the scale test model. The conclusions obtained in this study can provide a reference for a similar engineering practice.
