The rational support structure and construction method for large profile underground chamber were proposed based on the theory of support for openings in soft rock stratum.Based on the analysis of the support mechanism for realizing the stability of underground chamber,it was suggested to use bolting net-grouting and low pre-stressed anchor cable for the primary support and the full profile support by bolting-injection for the secondary support so as to form a composite bolting support structure.The specific support parameters of the chamber structure and the construction process were also given.The application and site monitoring show that such a composite support structure can meet the requirements for supporting the large profile underground chamber in soft rock stratum and can achieve both good technical and economic benefits.

The project implementation of South Water to North made stock water level of Danjiangkou reservoir increase from 157m to 170m,which resulted that partial species of rare plants would be submerged in this area.Thus,Danjiangkou botanic garden is planned and set up to save these plants.The paper introduces the concrete details of the plan on popularization of science,matching facilities,fundamental construction and environmental protection.
