Abstract：
Cuplock-type or fastener-type supporting system is generally used in design of super-high, super-heavy and large-span supporting system, but steel tubes of these two types are dense and inconvenient for construction. In this design scheme, statically indeterminate triangular steel truss group is used to replace steel tube supporting system. The former could not only effectively solve the difficulties in construction of super-high, super-heavy and large-span support, but also save construction cost, reduce construction period, guarantee construction and structure safety, having certain promotion values.
