Abstract
Disclosed herein is a support system that is temporarily placed below ground for preventing collapse of the excavated ground when a subway is constructed or a basement of a building is built. The excavated ground or load is supported by means of supporting members, the supporting members being pre-stressed by means of tensioning members and tendon support members serving to support the tensioning members. Consequently, the number of struts for supporting vertical piles and wales is considerably reduced so that obstacles in the under-ground space when it is excavated are removed. Furthermore, the constructional efficiency of the underground space is greatly improved, and the cost of construction is sharply reduced.

1-26. (canceled)
A pre-stressed support system for supporting the excavated ground load by using supporting members, a tendon support member being arranged about the central region of said supporting members along a longitudinal direction of said support members, a plurality of tendon support members each height being gradually decreased from the center of said supporting members toward both directions thereof and each being disposed at a predetermined interval, and tensioning members being fixedly supported on said plurality of tendon support members to thereby form an overall semi-parabola shape.
