Title:
FORMING METHOD FOR ASEISMATIC UNDERGROUND STRUCTURE
Document Type and Number:
Japanese Patent JP3495857
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a forming method for an aseismatic underground structure capable of preventing a large shear deformation from being generated on the underground structure without increasing the strength of the underground structure even when the underground structure and the ground are shaken to generate displacement by an earthquake.
SOLUTION: A lubricant is injected on the upper slab 1a of an underground structure main body 1 formed according to the normal method from the ground surface or from the inside of the underground structure main body to form a slide section 5 overlapped on the upper slab 1 a in layers by this forming method for the aseismatic underground structure. A material generating the frictional force, which is smaller than the frictional force generated between the soil on the upper slab 1a and the underground structure main body 1, between it and the underground structure main body 1 is used for the lubricant forming the slide section 5.
