“…Multilevel underground garages are an important element of urban agglomerations. Their construction, however, requires a strict technological process to protect the surroundings [1] as well as walls securing the excavation during its use [2]. Protecting the facility against infiltration of groundwater is a particularly difficult task; both against groundwater shown in the geotechnical documentation [3,4] and, more importantly, against water accumulating in the vicinity of the facility after its construction [5,6].…”

Multilevel underground garages are often an ambitious geotechnical task in urban agglomeration. Lower levels of foundation slabs are often located below the groundwater level, which requires effective protection of the structure against groundwater invasion. The constructor’s task is to design slabs and walls so that no cracks will form to allow groundwater infiltration. In practice, this requires the development of a correct recipe for concrete; moreover, all factors affecting the total state of normal and tangential stresses as well as technologies allowing for correct execution of the facility must be considered. Additionally, long-term destructive factors ought to be taken into account. The article presents problems that arose during the use of an underground garage, which occurred as a result of failure to take into account at the design stage some rheological processes, as well as the assessment of the possibility of using the facility despite the damage.

“…The building, whose floor and foundation slab is subject to technical evaluation, has several above-ground storeys, designed mainly for architectural offices and two underground storeys for garages. The building has a slab-and-column construction, with spacing of columns in axes of 8.1 m and dimensions 0.8 x 0.8 m x m. The ceilings are monolithic with a thickness of 0.4 m and 0.5 m. The building area of the underground part is approximately 4500 m 2 . The facility is located over 8 meters below ground level.…”

“…Internal force of cantilever pile body is calculated according to (12) and (13). The embedded segment of pile is calculated by " " method according to (19), (20), and (22). The soil pressure in the front of the pile is calculated according to (24) and the frictional effect between soil and surface of wall is not considered.…”

“…The forms of supporting structure of the retaining walls are single. Such as plate pile retaining wall, pull anchor pile retaining wall and door type pile retaining wall have their own conditions of use [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. High fill retaining wall is one of the biggest problems in the slope engineering because of its high investment and big constructing difficulties.…”

A new type of retaining wall, the self-balance retaining wall, is introduced in this paper. Based on the stress analysis, the calculation model and method are advanced about the retaining wall. A comparative analysis related to traditional retaining wall is carried out on stress and cost combining with an actual project. The results show that the idea of using upper gravity retaining wall as the resistance of lower retaining wall is clever and reasonable that the self-balance retaining wall has a very wide scope of application relying on the anchor tensile conditions rarely and that the self-balance retaining wall has a great economic value with low cost. The cost of the self-balance retaining wall is 50% compared with the cantilever pile retaining wall under the same conditions which has a good economic effect and application prospect.
