“…2. The conditional foundation modeled the work of the pile foundation in a plane setting: the load was applied directly to the level of piles tip, without taking into account the «pile-ground» friction forces or any dynamic effects during construction works (piles drilling, «moving load effect» [3], etc.). The width of the sole of the conditional foundation is assumed to be 30 m.…”

In the proposed research there were evaluated the factors influencing the distribution of additional pressure from ground construction on the linings of the subway tunnels. In recent years, the Department of Tunnels and Subways of the Emperor Alexander I St. Petersburg State Transport University has provided scientific support for many capital construction projects with geotechnical calculations of the buildings under construction impact on subway structures, both using analytical methods and mathematical modeling. The existing analytical methods allow us to evaluate the change in the additional pressure in the ground massive without taking into account the tunnel construction, while in reality the tunnel construction significantly changes the stress-strain state of the ground massive in the vicinity of the excavation. This factor was considered as the most significant, and together with it, there were evaluated the influence of the tunneling method and the influence of the applied geomechanical soil model on the calculation results.

Abstract. When there are many sources it is important to determine the sound power and directivity of each to determine their relative contributions to the noise problem. Any noise problem may be described in terms of a source, a transmission path and a receiver and noise control may take the form of altering any one or all of these elements. The aim of this paper is to suggest ways of reducing tram noise by technical and technological means.

Renewable energy is energy that is needed in this modern era. The need for electrical energy in the present is a primary need, much of the sustainability of human life is supported by the existence of electrical energy. We are in Indonesia where Indonesia is a country consisting of many islands, and 77% of Indonesia's territory is water. By utilizing the energy contained in ocean waves to make electrical energy by using sea wave power plants. Ocean wave energy harvsting, single pendulum pontoon systems, are one of the alternatives to energy problems in this world. Simulations were carried out to determine the electrical energy to be obtained from the from ocean wave energy harvesting, single pendulum pontoon system. The simulation was carried out with matlab software by controlling the variable amplitude of ocean waves 0.0125m, 0.025m, 0.0375m, 0.05 m, and 0.0625m. From the simulation results, current, power and voltage data generated from the ocean wave power generation system were obtained. In this study, the results obtained were different amplitude levels that had a real influence on the results of current, power and voltage generated from ocean wave energy harvesting - single pendulum pontoon system using minitab software to process data with a complete random design method. Where the higher the amplitude of ocean waves, the higher the value of the results of currents, voltages and power generated by single pendulum pontoon model from ocean wave energy harvesting.
