Deep foundation pit risk assessment method based on data fusion analysis

Номер: CN102880918A
Автор: Zhu Yanfei, Pan Weiqiang, Wang Jianhua, Chen Jinjian, Hou Yongmao, Shen Wei, Du Yi
Принадлежит:

The invention discloses a deep foundation pit risk assessment method based on data fusion analysis. A foundation pit engineering three-dimensional digital model constructed according to a computer aided technology can completely record and vividly display all pieces of information of foundation pit construction and can automatically generate a construction log and a monitoring report, so that a constructor or a technicist can execute operation conveniently, and the work for recording complicated construction information of foundation pit engineering is eliminated. By a finite element analysis technology and the conventional risk assessment method for static assessment, single-monitoring-item dynamic assessment and multi-monitoring-item relevance assessment, the shortcoming of fuzzy judgment of the conventional risk assessment method is overcome; through a large amount of data fusion, a series of risk sources in an engineering progress process can be comprehensively judged, and a targeted ...

Coal combustion-supporting hydrogel as well as preparation method and application thereof

Номер: CN102643705A
Автор: Chen Chaoyun, Pan Weiqiang
Принадлежит:

The invention discloses a coal combustion-supporting hydrogel as well as a preparation method and application thereof. The coal combustion-supporting hydrogel is prepared through the following steps of: (1) uniformly mixing 30-89% of metal nitrate, 5-60% of potassium chlorate, 1-3% of rare-earth elements, 5-30% of alkali metal hydroxide and 0-20% of sodium silicate, so as to obtain a mixture; (2) dissolving 3% of poly (N-isopropylacrylamide) and 30% of oxydol in water, and uniformly stirring, so as to obtain a solvent; and (3), dissolving the mixture in the solvent, so as to obtain the coal combustion-supporting hydrogel. The coal combustion-supporting hydrogel disclosed by the invention is non-corrosiveness, is stable in property, can be easily adsorbed to the surface of coal powder so as to form a loose porous combustion adjuvant layer, can be directly mixed with coal by virtue of a spraying device, and is convenient in use. By utilizing the coal combustion-supporting hydrogel disclosed ...
