The TRINCEE programme allows the design of "draining trenches" systems, created for the stabilisation of slopes, the site of possible landslide events, consisting of incoherent soils in the presence of water tables.‎ The programme considers the effect of earthquakes in the calculation.‎ Calculation method The TRINCEE programme uses the global limit equilibrium method, considering the potential slip surface parallel to the ground plane (undefined slope hypothesis).‎ Mohr-Coulomb's criterion and Terzaghi's principle of effective stresses are used in the calculation.‎ Input dataThe data required by the TRINCEE programme are the following: - Slope of the topographic profile; - Physical-mechanical characteristics of the soil; - Position of the water table; - Permeability coefficients of the soil; - Height of the trench and slope of its walls with respect to the vertical; - Seismic characterisation of the site under examination .‎ Output dataThe results proposed by the TRINCEE programme are the following: - Factor of safety at the current state of the slope; - Maximum available factor of safety of the slope; - Trench spacing and base; - Hydraulic efficiency at steady state; - Factor of safety at 50% of hydraulic efficiency; - Factor of safety at 90% of hydraulic efficiency .‎ Standards- NTC 2008 (Technical Standards for Construction) and its integrations - D.‎M.‎ 88 + D.‎M.‎ 96 - NTC2018 - Circular 21 January 2019 n.‎7 C.‎S.‎LL.‎PP
