Structural design and verification of landfill constructions
Structural calculations must be conducted for drain pipes on bottom sealing, tunnels, manholes and penetration constructions. In case of landfills, the attention must be payed to unfavorable bedding conditions of the domestic waste with significant settlement and high service temperatures. Manholes sometimes have to be designed for seismic influences. In order to achieve economical and load bearing constructions on the long run, extensive theoretical, experimental and in-situ tests have been conducted. Possible influences and bedding material for manholes and drain pipes were examined. Special requirements have been set for structural integrity and permeability of the drain pipe bedding. A development of so-called Mixture 9 took place on the Soil Engineering department of the University of Munich. Dr. Albert Hoch attended the experiments theoretically and along with the LFU Munich developed them until the practical applicability.
