ENVIRONMENTAL SAFETY OF CONSTRUCTION OF OIL AND GAS FIELD ACCESS ROADS IN WESTERN SIBERIA
Pages 145 - 151
The paper presents the results of the field study of the subsidence following the implementation of one of the road building methods. The field study was performed in the area alongside oil and gas field access roads built in the loose marshy ground (peat). The paper provides a description of the geosynthetics installation technology. Outdated road building technologies designated for weak road base conditions feature high consumption of materials and energy and substantial anthropogenic impact on the environment. These technologies comprise complete or partial replacement of the ground by sand, road metal, or macrofragmental material combined with timber as the reinforcing element of the base (a plank road). The objective of the field study was to develop an ecologically safe technology capable of reducing the anthropogenic impact on the environment and improving the strength and the operating safety of the road structure. The field study has proven that the aforementioned objective may be attained through the application of geosynthetic materials designated for the improvement of the bearing capacity of the weak road base. Geosynthetic materials and structures of the road subgrade ensure high speed of construction, high quality and reliability of the road structure, reduction in the consumption of materials and energy to assure the ecological safety of construction of oil and gas field access roads. Earlier, the author used the qualimetry method to assess the ecological safety. This method is used to assess the ecological safety in points. The assessments have proven that the reinforced base technology is preferable to the method of complete or partial replacement of the ground. Projection of the subsistence development pattern that makes it possible to evaluate the safety and the serviceability of the proposed solution is also an important efficiency factor. The field study involved a section of the oil and gas field access road outstretched along the oil transportation route that connected three Salym oil fields in Western Siberia.
