DEBRIS FLOW CHECK CONSTRUCTIONS SITUATED NEAR THE MOUTH OF RIVERS OF THE SAKHALIN ISLAND
The significant part of roads and railways of the Sakhalin Island are located in the coastal zone of the sea, in the lower part of the debris flow transit zone. Debris flows cause blockages and damage to the roadways. In some areas of the island are sites where the number of debris flow basins is 30-40 per km. Basically, these are slope debris flows, which are formed annually during precipitation of liquid precipitation, and whose volume can reach 500 m3. At the same time, debris flows can play an important role in the formation of beaches and protection from abrasion due to the removal of material to the mouth of the rivers. Transport of debris flow material to the coastal zone on the Sakhalin Island is carried out on the coasts of the Gulf of Patience, the Gulf of Aniva, the Tatar Strait, etc. Beach savings are the best of its natural protection against destruction. Therefore, the need to build seepage facilities is due not only to the need to protect the roadway, but also the importance of transporting debris flow material to the beach area. Characteristics of debris flows in the coastal zone of the island differ in a number of parameters, such as the volume of debris slides, the frequency of formation of debris flows, the type of debris flows, the size of carried fragments of rocks; therefore, when choosing a debris flow protection facility, it is necessary to be guided both by the parameters of debris flows and by the role of debris flows in the formation of beaches. The paper examines the current state of water chute and debris flows chute under the roads in the near-mouth parts of debris flow rivers, as well as the expediency of selecting debris flow protection structures depending on the characteristics of debris flows.
