Abstract


Shallow bias often encountered in the construction of railway, highway, municipal engineering, soft rock tunnel. With the popularization and application of the principles of Austrian law, construction support method has improved by leaps and bounds since the eighties of the last century, to take fast and effective support for advance support, steel frame, radial anchor net spray such as concrete measures to effectively enhance self-stabilizing capacity of the surrounding rock, greatly accelerate the construction schedule, while security, quality has also been a strong protection. Various industries at home and abroad in addition to the construction methods and technical means great progress, more and more attention in advance geological prediction in tunnel construction work, the engineering geological radar to geological forecast during construction. In this paper, the construction of the Shaoshan One tip Bu-dong tunnel group instance, the use of on-site construction technology Countermeasures surrounding rock testing analysis, numerical simulation analysis and monitoring measurement and research methods, weak surrounding rocks in highway tunnel construction process, the main content of the study are: first clear definition of the shallow geological characteristics and engineering properties of soft rock, made a more comprehensive analysis of the stability factors affecting the soft surrounding rock tunnel; 2. weak surrounding rock road The characteristics of the tunnel system summarizes the weak surrounding rock highway tunnel excavation and support mechanism and methods of construction. Of soft surrounding rock the highway tunnel excavation method is compared, that the two-step method has advantages, and ensure the safety of the construction on the basis of and ensure project quality and duration. Support for soft rock tunnel excavation can be the anchor, sprayed concrete and steel support flexible support to be controlled. For some lots that require special handling, can be used in the construction process in the tunnel at the bottom of timely additional temporary invert, the pipe roof grouting and the additional locking pin, bolt, and other methods to achieve the purpose of controlling the tunnel deformation; 3. Detailed analysis shallow tunnel construction technology and force characteristics; establish the construction of the anti-tip Bu hole tunnel collapsed measures with the collapse of the contingency plans of the construction process numerical simulation to study the changes of the plastic zone, the internal forces of the Early Support hole the surrounding deformation and excavation footage and vault sink relationship. See from the results of the numerical analysis, the way of selection of excavation and support of tunnel construction is reasonable. 5. Tunnel arch sinking tunnel the surrounding displacement convergent LINING monitoring measurement, in order to feedback the tunnel excavation and support the reasonableness of the construction process, and also verify the reliability of numerical simulation. In this paper, the actual project as the research object, and use of research results to the engineering practice, resulting in a significant economic and social benefits, has a certain reference value for similar projects.
