Изобретение относитс к строительству жилых, общественных и промышленных зданий , возводимых в сейсмических районах и главным образом на склонах массивов.The invention relates to the construction of residential, public and industrial buildings erected in seismic areas and mainly on the slopes of arrays.

Известен фундамент сооружений, примен емый в сейсмических районах 1.The known foundation of structures used in seismic areas 1.

Недостатком этого фундамента вл етс невозможность воспри ти горизонтальных составл ющих сейсмических нагрузок.The disadvantage of this foundation is the impossibility of perceiving the horizontal components of seismic loads.

Наиболее близким по технической сущности к изобретению вл етс фундамент зданий, сооружений, возводимых на склонах, включающий размещенные вдоль склона опоры, соединенные в каждом р ду св з ми, и размещенные на опорных элементах башмаки 2.The closest in technical essence to the invention is the foundation of buildings, structures erected on slopes, including supports placed along the slope, connected in each row by ties, and shoes 2 placed on the supporting elements.

Недостатками указанного фундамента вл ютс разработка грунта основани сложной ломанной конфигурации, укладка сплошной железобетонной ребристой плиты под весь контур стро щегос здани , сооружени и следовательно, повышенный расход стали и бетона, высока трудоемкость возведени фундаментов и меньша надежность при сейсмических воздействи х, так как железобетонна плита уложена по верху склона скального массива без его требуемого заглублени The disadvantages of this foundation are the excavation of the base of a complex broken configuration, laying of a solid reinforced ribbed slab under the entire contour of the building, construction and, consequently, increased consumption of steel and concrete, high labor intensity of foundation construction and less reliability under seismic effects, as the reinforced concrete slab laid on top of the slope of the rock massif without its required depth

В грунт основани , что не исключает возможности сползани всего массива, в особенности при падении пород по уклону. Кроме того, конструктивное решение фундамента здани , сооружени в целом при воздействии сейсмических инерционных сил может вызвать нарушение устойчивости склона при напластовании .Into the bottom of the base, which does not exclude the possibility of sliding the entire array, especially when rocks fall on a slope. In addition, a constructive solution to the foundation of a building, a structure as a whole, when subjected to seismic inertial forces, may cause a violation of the slope stability during bedding.

Цель изобретени - повышение сейсмостойкости и снижение материалоемкости фундамента.The purpose of the invention is to increase the seismic resistance and reduce the material intensity of the foundation.

Цель достигаетс тем, что в фундаменте зданий, сооружений, возводимых на склонах, включающий размещенные вдоль склона р ды опор, соединенных в каждом р ду св з ми, и размещенные на опорных элементах башмаки, опоры выполнены в виде The goal is achieved by the fact that in the foundation of buildings, structures erected on slopes, including rows of supports placed along a slope, connected in each row by ties, and shoes mounted on supporting elements, the supports are made in the form

15 заглубленных в тело склона бетонных и железобетонных элементов, причем железобетонные элементы выполнены большей длины, чем бетонные, и размещены с верхней или нижней части склона, а св зи выполнены 15 concrete and reinforced concrete elements buried in the body of the slope, the reinforced concrete elements being made longer than the concrete, and placed on the top or bottom of the slope, and the connections are made

20 в виде ребер и расположены на поверхности склона.20 in the form of ribs and located on the surface of the slope.

Claims

FIG. 1 shows the foundation in plan; in fig. 2 - the same section; in fig. 3 - the same, option of performance of the base. The foundation consists of the ribs 1, the concrete element 2, the reinforced concrete element 3, the supporting shoe 4, the columns 5. The mechanical connection of the component elements is as follows. Concrete elements 2 are arranged along the natural slope of the mountain relief, which serve to absorb horizontal and vertical loads. In addition, the concrete elements 2 provide the dressing of the cut layers by concreting the supporting basmaks 4 under the point foundations. The reinforced concrete elements 3 are arranged to receive the same loads, however they serve as the main pillars of the foundations of the whole building as they creep into bedrock. Reinforced concrete elements 3 are arranged in the upper or lower part of the slope, where it is more effective according to engineering geological and other data. They are made in the form of bored or other types of piles and serve as stops for the entire foundation if they are located in the lower part of the slope; when arranging the piles in the upper part, the structural foundations of the building are suspended from them. The number and dimensions of reinforced concrete elements 3 are determined by calculation taking into account additional loads caused by the reaction of the fins 1, connecting concrete elements 2 and reinforced concrete elements 3 between themselves. Ribs 1 are made of reinforced concrete and follow the slope profile in the longitudinal direction. Such a foundation structure enhances the seismic resistance of the foundation of buildings erected on slopes and reduces their material capacity. The invention The Foundation of buildings, structures erected on slopes, including a number of supports placed along the slope, connected in each row of connections and placed on the supporting elements of shoes, characterized in that, in order to improve the seismic resistance and reduce the material intensity of the foundation, the supports made of concrete and reinforced concrete elements recessed into the body of the slope, the reinforced concrete elements being longer than concrete and placed on the top or bottom of the slope, and the connections are made in the form of ribs and On the surface of the slope.
