Risk Management Research Of The Flat Hole Project

In the construction of modern building project, the risks almost exist anywhere and anytime. For the building project, which is on the big scale, long period, and also whose product characterize singleness, the more uncertain factors and bigger risk exist in the processes of construction. As a subprogram of national defense project, the horizontal holes project, because of its character of politics, secrecy, and un-subcontract, brings more risk under the construction. How to manage the risk under the construction of horizontal holes project is the precondition and foundation, which ensure that the experiment project is successfully completed.According to the flat hole project, the author research object ,in the thesis, direct that the operators are lack of risk consciousness and safe accidents occurred frequently to research .By reference the flat hole project's constructed technology summarizes, constructed summarizes, constructed log act. completed information, identifies quality risk ,schedule risk and safety risk in the flat hole project .adopted experts'advices and use risk listing to modificated and consummate this identified risks ,formulated reasonable questionnaire , choose investigative object by probability delimitation sample idea ,accounted and analyzed the single risk affair's importance evaluate guideline with I×P and fault tree analytical method .ensured the sixth risk affair in each kind of risk was importance risk affair ;combine work experience and inquired research ,referred to datum ,the technology measures was mapped out to each naps of risk affairs ,and the technology measures was mapped out to each kinds of risk affairs; For this hole project constructed risks'holistic management, took advanced manage way ,wholesome organizations, assure systems to control.According the result of the research, it is indicated that, the important event bringing quality risk is collapse, the quality problem of material, sap breadth difference, beforehand burying piece's situation excursion or bearing lack, construction scheme maneuverability bad and unusual anchor's force is unconformity. the important event of schedule risk is mainly the untimely material provision, Construct machine and equipment's performance isn't good ,unreasonable demand in work time, engineering design occur modify ,superior departmental interfere and project management assort with badly. the important event of security risk is getting out of line to work and is removing danger without timeliness to cause the rock to slide, Dozen remnant hole, pecans operation to get rid of remnant hole ,machine and equipment accident in work , temperately shoring isn't in time and defend in high work unsuitable. To these risks, the controlling ways were to adopt advanced construction means, stronger the operation rules, perfect expected and prevented, enhance communicates and corresponds, carried out bylaws. Adopt information-based construct and dynamited-design and set up whole risk manage organizes and assured systems to manage the whole flat hole engineering.
