The prediction technics of tunnel sets with complex three dimensional configuration stress state with allowance for relative influence and building sequence

The three dimensional stress distribution in tunnel set with allowance for relative influence and building sequence is investigated. To complete the task the finite  elements analysis was  used. The values of stress concentration factor and conformities of stress distribution in the «lining – mass» system are estimated. The relative influence of each tunnel in tunnel set with allowance for building sequence is identified.

The designing of the constructions of the pillar underground station with applying of the low-settle building technology

The intelligent technology of designing of the constructions of pillar  underground  station is adduced. Station is building with applying of low-settle technology, which takes into consideration main stages of the building process. The scheme of interaction of the system «support lining-soil massif» was accepted as basic scheme of calculations. The calculations of the stress-strain condition of constructions was performed with applying of finite-elements method.

The determination of the volume stress-strain conditions of the soil massif in the face area of the tunnel in conditions of drafting with using of contledge of the face

In this learned article the analysis of reinforcing effect, which appears during the process of the drilling of tunnels with using of contledge of the face which applied in tunnel boring machines, is adduced. By applying of the finite-elements method the family of graphical relations, which reflects the processes of the development of displacements, is approached. For the reason of analysis of these relations the optimal value of contledge of the face if maximum permissible displacements of the earth surface are known have been suggested. The influence of the main strength characteristics of Couloumb – Mohrs’s theory of strength on stability of the face of the tunnel and the necessary value of contledge of the tunnel’s face are defined.

Geomechanical substantiation of parameters of the fastening of railway tunnels in the conditions of the North Caucasus

The article presents the rationale of temporary supports used in the drilling of new mines, which provides for the construction of model projects of reconstruction of old tunnels. Finite-element method analyzed the changes of stress-strain state containing tunnel complex array during the drilling of new mines. Based on the analysis, a number of findings to explore the possibility of reducing the thickness of the permanent support of new mines in tunnel complex - the new tunnel, and transport and drainage culvert.

The determination of the volume stress-strain conditions of the rock massive with the circular outline mining ensrined with the anchors

In the article the analysis of consolidating effect from application of the anchor fastening, which using at driving of transport tunnels in the conditions of North Caucasus is produced. The change of the stress-strain condition of the rock massive, which is weaked by the mining of the circular outline is certain with the finite-elements method. On the basis of the executed design the row of graphic dependences, which describes changing of the sizes of limitary areas depending on strength and deformational properties of the rocks. Due to results of the conducted work the direction of further researches is seted.
