摘要

The 710m-long Penchala tunnel is the first underground civil structure of the Kuala Lumpur highwayrnsystem. It is a twin-bore tunnel and each bore has a horse-shoe shaped section with an excavated arearnof 118-144m2. The ground conditions vary from residual soils to fresh, strong granites and thernoverburden from a few meters to a maximum of 115m. Given the importance of this tunnel and thernrelatively limited experience of Malaysia in constructing tunnels of this dimension, the constructionrncontract was procured through international tendering, admitting proposals with alternative solutionsrnfor design and construction. This paper illustrates how an efficient combination of empirical,rnanalytical, and observational approaches, allows to develop a flexible Construction Design and tornspeed the execution. Moreover, it gives a quick overview of the optimization introduced by thernwinning, Alternative Solution proposed by the Designer Geodata together with the Sub-ContractorrnCMC, who excavated the tunnel, over the original Tender Design. The tunnel excavation and supportrnwere completed in May 2003. The example represents certainly another successful case of technologyrntransfer from Italy to abroad.
