Abstract Research purpose: Nowadays the principle of "Take drainage as the dominant factor" is still followed in design and construction of long tunnel in karst zone. It not only causes serious geological disaster occurring in construction and service of tunnel, but also causes water and land resources damaged and environments of ecology and geology worsened, even directly influences the sustainable development of tunnel because of unique characteristics of karst strata. This paper is written for causing attention to the problem of environmental geology while constructing long tunnel in karst zone, changing design and construction concepts of design and construction of long tunnel in karst zone in order to make design and construction conforming to the basic policy of state and keeping the strategy of sustainable development.
Research method: The formation of geological disaster and its direct relation with environment worsening are demonstrated through analysis of the influences on water and land resources by existing design principle.
Research conclusion: It is proposed that the fully closed design scheme should be adopted for key area, namely in combination with advanced geological survey, the pre-reinforcement should be conducted to the ahead burst mud area with complex geology before geological disaster of tunnel occurs in order to make no worse of environmental geology.
