Karyukinab Environmental Center Sustainable Management of Natural Resources 53 Mira, Krasnoyarsk, 660049, Russia State Enterprise of the Krasnoyarsk Territory “Krasnoyarsk Research Institute of Geology and Mineral Resources” 55 Mira, Krasnoyarsk, 660049, Russia Received 22.11.2014, received in revised form 15.12.2014, accepted 09.02.2015 The refraction survey is based on registration of refraction elastic waves away from the source. <...> You can get the mentioned data on condition that the elastic waves velocity from layer to layer in the ground gets higher in the depth. <...> However, there are cases when there occur low-velocity layers among high-velocity ones in the ground in question. <...> In the worked-out algorithm no new software packages have been invented, but the opportunities of already known software packages have been used (RadExPro, in our case), along with using miscellaneous calculations and graphic editors. <...> All rights reserved * Corresponding author E-mail address: vasya-kun@mail.ru # 108 # Vasiliy A. <...> Developing the Algorithm of Delineation of Low-Velocity Ground Layer… <...> Разработка алгоритма выявления низкоскоростной прослойки грунта в более высокоскоростном слое в рамках метода преломленных волн для оценки сейсмической безопасности техносферных объектов В.А.
