Abstract

Способ строительства преимущественно высоких и высотных зданий и сооружений на неравномерно сжимаемых грунтах, согласно которому после сооружения очередной группы из одного или нескольких этажей строения производят измерения осадок фундаментов, средних наклонов верхнего перекрытия над этой группой этажей и средних наклонов верхних перекрытий над всеми ранее сооруженными группами этажей, а по результатам измерения и их анализа судят о деформациях основания и напряженно-деформированном состоянии строения к моменту измерений и до полного возведения строения, а также о необходимости воздействия на грунт или фундамент, отличающийся тем, что вначале фундамент сооружают из расчета не на полную нагрузку от строения, а на ее часть, например от половины строения, в процессе сооружения этой части строения производят измерения деформаций фундаментов и наклонов перекрытий, по ним оценивают действительные характеристики деформируемости грунтов, напряженно-деформированное состояние строения на момент измерений и на полное его возведение, а также необходимость повышения несущей способности фундаментов, после чего в случае необходимости выполняют работы по повышению несущей способности фундаментов путем увеличения размеров фундаментов, упрочнения грунтов под фундаментами, например, путем инъекции закрепляющих растворов, дополнения ранее сооруженных фундаментов сплошной железобетонной плитой, вдавливаемыми, завинчиваемыми или буронабивными сваями, причем повышение несущей способности фундаментов осуществляют только в той части, в том объеме и на том уровне высоты строящегося здания, сооружения, которые A method of constructing predominantly tall and tall buildings and structures on unevenly compressible soils, according to which, after the construction of the next group of one or several floors of the structure, measurements of foundation precipitation, the average slopes of the upper floor above this group of floors and the average slopes of the upper floors above all previously constructed floor groups , and according to the results of the measurement and their analysis, they judge the deformations of the base and the stress-strain state of the structure at the time of measurement and to the floor erection of the building, as well as the need for exposure to the soil or foundation, characterized in that at first the foundation is constructed not to fully load the building, but for its part, for example, from half the structure, in the process of constructing this part of the structure, measurements of the deformations of the foundations and slopes of the floors, they evaluate the actual characteristics of the deformability of soils, the stress-strain state of the structure at the time of measurement and its full erection, as well as the need to increase the foundation abilities, after which, if necessary, work is carried out to increase the bearing capacity of the foundations by increasing the size of the foundations, hardening the soils under the foundations, for example, by injecting fixing solutions, supplementing the previously constructed foundations with a solid reinforced concrete slab, pressed, screwed or bored piles, and increasing the bearing capacity of the foundations is carried out only in that part, in the volume and at that level of the height of the building under construction, structures that

A method of constructing predominantly tall and tall buildings and structures on unevenly compressible soils, according to which, after the construction of the next group of one or several floors of the structure, measurements of foundation precipitation, the average slopes of the upper floor above this group of floors and the average slopes of the upper floors above all previously constructed floor groups , and according to the results of the measurement and their analysis, they judge the deformations of the base and the stress-strain state of the structure at the time of measurement and to the floor erection of the building, as well as the need for exposure to the soil or foundation, characterized in that at first the foundation is constructed not to fully load the building, but for its part, for example, from half the structure, in the process of constructing this part of the structure, measurements of the deformations of the foundations and slopes of the floors, they evaluate the actual characteristics of the deformability of soils, the stress-strain state of the structure at the time of measurement and its full erection, as well as the need to increase the foundation abilities, after which, if necessary, work is carried out to increase the bearing capacity of the foundations by increasing the size of the foundations, hardening the soils under the foundations, for example, by injecting fixing solutions, supplementing the previously constructed foundations with a solid reinforced concrete slab, pressed, screwed or bored piles, and increasing the bearing capacity of the foundations is carried out only in that part, in the volume and at that level of the height of the building under construction, structures that provide safety and allowable level of deformation of the building until its completion.
