The article describes and discusses in detail the process of inspection and testing of the railway bridge on the Uchkurgan – Tashkomur stage km 17+494, carried out by specialists of the Kyrgyz State University of Construction, Transport and Architecture (KSUCTA) on the basis of the contract  with  the Mostootryad  SE NK Kyrgyz railway for the purpose of assessing the technical state of pavement design, evaluation of its conformity to requirements of standard documentation and preparation of technical findings with conclusions and suggestions for further exploitation of the bridge and increasing its operational safety.

Reducing the dynamic impact of a landslide on buildings and transport structures in the village of Toktogul, Uzgen district of the Kyrgyz Republic

In the Kyrgyz Republic, there is a significant increase in landslide activity against the backdrop of ongoing climate change, especially in the southern mountainous regions of the country. The volume of soil during a landslide in this region can reach tens and hundreds of thousands of cubic meters, and in some cases more. The rate of landslide displacement ranges from several meters per year to several meters per second. The purpose of this study is to unload the landslide area to protect the population, roads and other structures of the village of Toktogul, Uzgen district of the Kyrgyz Republic. This landslide area was studied on the basis of field research on the ground and the results of desk work. The sliding of soil masses in the area can cause destruction and debris of residential and administrative buildings, roads and power lines, as well as injury and death. Considering the equilibrium of the system of forces acting on the subsidence soil mass of the slope section and analyzing them, measures for unloading the landslide body in this section are proposed. The proposed longitudinal profiles of drainage channels to reduce the moisture content of subsidence soil and transverse profiles of developed soil to reduce the weight of subsidence soil are presented. Based on the results of processing research data and analysis, it is recommended to reduce the weight of unstable (subsidence) soil by stepwise development along the slope of the site and transporting it up to 5 km for subsequent brick production. It is also recommended to protect subsidence soil from waterlogging by installing drainage channels. Based on the results of the research, a real project was developed to protect the site from landslides near the village of Toktogul. The proposed measures make it possible to reduce the risk of a landslide in the area under consideration using methods and technical means that are inexpensive and accessible to government agencies and local administrations.
