DC-Pit calculates construction pit walls: bore pile walls, diaphragm walls, sheet pilings, girder plank walls and MIP (Mixed In Place) walls. A construction pit wall, consisting of different sectors and optionally inclined at an angle, is loaded by:
We also consider that in case of an inclined wall, the earth pressure depends on the angle of the inclination. Additionally, the gravity axis runs inclined with the inclined walls, and horizontal and vertical walls are converted in components parallel and crossways to the system axis. The calculation of the section forces for the wall unit is carried out at the polygonal bar construction, considering thus eventual bends in the gravity axis. The pit soil may be arbitrarily layered. The program considers automatically the water level by using the specific weight under uplift. The ground surface may have – outgoing from the wall head –up to two slopes or ground surface offsets and one slope in the pit. The program determines automatically the effects on the earth pressure distribution and the effects with imposed loads on the ground surface, such as e.g. the effect distribution of limited imposed loads with pressure at rest according to Fröhlich. In case of different water levels in front of and behind the wall and the permeable layers, we consider the flow pressure. Additionally, the program calculates the safety against the hydraulic ground failure. You may select various redistribution figures for the earth pressure. The program calculates the wall as a cantilever beam or as a single-span or multi-span girder. The wall foot may be horizontally movable, horizontally fixed (e.g. in a rock), fixed according to Blum or continuously supported, optionally with an elastic support, which may be adapted to the passive earth pressure as a maximal value, if required. Anchors may be applied as bearings (calculation of the anchor force = supporting force), or as predefined forces (anchor force = concentrated load). You may optionally iterate the required wall length in the different excavation stages. The program outputs the earth pressure distribution, the loading, the section forces of the wall and the deformations in detail. The required anchor lengths may be determined with the analysis of the deep sliding plane, with a detailed printout of the anchor position, the inclination, the force, length and safety factor, as well as optionally the forces that influence the analysis. The program DC Pit gives many special approaches at your disposal to be able to calculate excavation pits following German, Austrian, Swiss or European codes as well as the German EAB (Recommendations of the study group excavation pits) and EAU.
