Title:
DESIGN AND CONSTRUCTION MANAGEMENT FOR WATER SEAL TRAP BEDROCK, AND MAINTENANCE MANAGEMENT METHOD
Document Type and Number:
Japanese Patent JP3389982
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To properly manage water sealing by grasping underground water behavior in a bedrock with precision higher than that of a porous substance model heretofore used.
SOLUTION: In a design method for a water seal trap rockbed storage pertaining to this invention, first, as shown in Fig 2, a water seal trap bedrock storage 4 provided with a storage cavity 2 excavated and formed in a fissured bedrock 1 and a boring hole 3 for water seal to supply water to the periphery of the storage cavity is modeled as an analysis model to be used in a fracture network model at a step 101. Secondly, a produced analysis model is analysed and underground water behavior at the periphery of the storage cavity 2 is evaluated at a step 102. Thirdly, by using the evaluation result, a design for the water seal bedrock storage 4 is effected at a step 103.
