terior space and changes in the unity of the material texture and contrast the rich interior colors and harmonization, have helped to create a good internal environment, the elimination of the underground environment on people39。 s poor physical and psychological effects. ④ for structural design and construction to create favorable conditions. Underground construction of the main features of the structural design is a big load, so in the architectural design, from layout, column work options to determine the areas 7 of story should be for the structural design of the economy, create conditions reasonable. The construction of underground construction is rather plicated, the design should be to simplify the construction and shorten the duration and the use of advanced construction technology to create favorable conditions and minimize the ground during the construction period of the normal activities such as transportation and so on. As the underground construction of the building structure is different from the specificity of the upper part, involving the design, construction technology, environment and soil mechanics, such as technical progress in a series of problems in engineering applications engineers often encounter the following problems: (1) of the underground structures of conventional reinforced concrete structures are mainly ordinary reinforced concrete structural system used in the existence of largescale underground structure of the high cost, even crosssection structure, and the impact of depth of underground structures, construction progressing at a slow pace, as well as the shortings of a waste of construction materials, should the new system, the introduction of construction materials and structural design of underground structures to meet the modern requirements of the development of underground space, with limited resources for better results. (2) as the cause of urban rail transit development, urban towel existing and new buildings and subway lines crisscrossing the upper part of structure is at the top of the subway tunnel, the conventional reinforced concrete structure of care for the larger crosssection of the underground architectural space also have a greater impact. Workers should be the actual situation in innovative technology, choose a reasonable form of structural transformation of the construction and 8 related measures to ensure that the subway project and the safety of the upper structure and to minimize the impact of the underground space. (3) as an urban development strategy of threedimensional one, highrise buildings will continue to challenge the next new height, and construction will continue to increase in the floor, vertical wall structure is not posit the lower part of the greater crosssection, located in Building the lower part of the basement of the building material the use of space caused by an enormous impact。 another aspects of underground construction is the future direction of space, largespan, the vertical ponent will be an inevitable increase in crosssection. Therefore, the vertical crosssection configuration to optimize materials and even to improve the underground construction of the space is designed to be taken into account. (4) as a result of largescale development of underground space and underground construction and use of the water requirements of more demanding, long, extrawide development of the underground construction joints or less, regardless of the trend is subslit, regardless of current underground construction joints maximum length of over 800m, long and spacious underground construction specification requirements higher than the conventional approach has solved the structure of superlong concrete shrinkage, temperature, deformation and so on, the ground floor of building largescale crack the case more and more. On the other hand, in order to prevent occurrence of cracks to increase the floor, roof and side wall of the reinforcement, so that the sharp increase in the basement of steel, it is therefore necessary to seal a device able to reduce power consumption Ultra contraction of a long side wall and bottom of the internal force and deformation temperature, effectively improve the problem of cracking of underground construction. 9 (5) as a result of underground construction in the fire reached the bottom of the lift requirements for the highlevel and ultrahighrise building, fire pit at the end of the lift is often deeper than 2m, the largest reach 3m. Conventional reinforced concrete pile cap by inch: the requirements of antipunching greater thickness, and then caused by the lift at the end of the partial concave pits and the requirement of the cap to meet the bending, shear, antipunching conditions, go on local concave The site needs to be integrated with the cap around the basically the same thickness, such as the cap, in the partial concave , the caps into a partial thickness of 6m, the amount of concrete and reinforced caused a significant increase, while the base pit at the bottom of the second excavation deeper than 5m, the safety of the Foundation have been affected. Modern underground structure calculation and analysis of three major aspects: 1) the overall structure of underground construction, including both groundlevel structures with basement soil guitar and pure bination of overall analysis of the soil underground construction bined with the overall analysis of colorectal。 2 ) underground construction structure steel concrete posite structure ponents of the calculation of portfolio analysis。 3) against the practice of underground structure calculation。
