Free Vibration of Shallow-spherical Shell Xianqin Hou Architecture and Civil Engineering School, Inner Mongolia University of Science and technology, Baotou, 014010, China Email:89239730@qq.cn Keywords: shallow-spherical shell; free vibration;exact solutions; Bessel functions; harmonic functions.
Shallow spherical shell is one of the structure shapes and is adopted extensively in engineering.
Introduction Among the spatial structures, the shell structure, which has sleek type and good structural properties, is favored not only by the architects, but also being beloved by structural engineers.
Although this method, which is called practical solution method, is not complete theoretically, it is still widely used in engineering because of its simpleness.
Although the practical solution is easy and convenient to use in engineering, compared with the exact solution, there are still some errors.

Improving Technological Processes for Borehole Drilling in Construction Using Vibration Impact Vladimir Verstov1,a, Antonina Judina2,b* 1,2Saint Petersburg State University of Architecture and Civil Engineering Vtoraja Krasnoarmejskaja ul. 4, St.
Introduction Modern technologies of using vibration during construction have become possibly due, mainly, to Russian researcher and engineers [1–10].
They are used for engineering-geological sampling, driving displacement piles, freezing works and other methods of stabilizing weak soils, inserting explosives into soils and other works.
Vibration-rotating drilling can be used in both soft and hard soils for engineering-geological research and other types of boreholes for construction purposes with the depth up to 50 m and more.
