Development of Rational Method of Design of Soil Nailing System in Granular Soil

On-site stormwater detention is widely used in Australia as a means of controlling the increased storm discharges from urban consolidation projects. However, unless the maximum permissible site discharge is correctly determined, the local piped drainage system may be overloaded. This paper presents a generic methodology that integrates detention storage behaviour with drainage design theory in such a manner as to protect the entire length of the downstream drainage system. Its generic nature facilitates its universal application to all systems, protecting these valuable community assets throughout their service lives.

The Conclusion points out that the preceding seven chapters’ examples and case studies have revealed some expected, and some unexpected conclusions. The six main cases revealed some expected uniformity in the leaders’ selection of rational methods. There was less uniformity, however, in the choice of the methods they emphasized, whether due to their personal preferences or to the circumstances they were facing. Two unexpected findings were the addition of a seventh appropriate rational method—learning—and the prevalence of dual-leadership teams. The conclusion goes on to suggest that this book’s theory and approach should be applied to versions of military leadership and to the political leadership of contemporary democracies.

Earthquake Action

Slope anchorage structure of soil nail is a kind of economic and effective flexible slope supporting structure. This structure at present is widely used in China. The supporting structure belong to permanent slope anchorage structure, so the design must consider earthquake action. Its methods of dynamical analysis and seismic design can not be found for the time being. The seismic design theory and method of traditional rigidity retaining wall have not competent for this new type of flexible supporting structure analysis and design. Because the acceleration along the slope height has amplification effect under horizontal earthquake action, errors should be induced in calculating earthquake earth pressure using the constant acceleration along the slope height. Considering the linear change of the acceleration along the slope height and unstable soil with the fortification intensity the influence of the peak acceleration, the earthquake earth pressure calculation formula is deduced. The soil nailing slope anchorage structure seismic dynamic calculation model is established and the analytical solutions are obtained. The seismic design and calculation method are given. Finally this method is applied to a case record for illustration of its capability. The results show that soil nailing slope anchorage structure has good aseismic performance, the calculation method of soil nailing slope anchorage structure seismic design is simple, practical, effective. The calculation model provides theory basis for the soil nailing slope anchorage structure of seismic design. Key words: soil nailing; slope; earthquake action; seismic design;
