(OP)
We are currently planning a tunnel for a small hyro project and one of our engrs. recommended to use rectangular shaped tunnel instead of an arc roof tunnel to save money for tha arc rib support..what would be the disadvantage if we use rectangular shaped when it comes to quality of the support..
