This project belongs to the field of mountain architecture. In Chongqing, Guizhou and other southwestern regions of our country, high-rise penthouse buildings have developed rapidly in recent years because they are built against mountains and have little impact on mountains and surrounding environment. However, due to the large load and uneven stiffness distribution, high-rise suspended buildings are different from the design of conventional structures in terms of analytical models, performance evaluation, design points, etc., and are also different from the construction of plane structures in terms of construction organization. In addition, the complex environment of mountainous slopes in which the building is located brings huge challenges to the design and construction of high-rise suspended buildings. This project carries out systematic research on the seismic design and vibration reduction of high-rise suspended buildings, slope support of multi-level steep slopes, the construction of individual high-rise suspended buildings, and the construction of high-rise suspended buildings groups, forming four innovative technologies: 1) Seismic analysis of high-rise suspended buildings and vibration reduction technology Through static elastoplastic analysis, it reveals for the first time the mechanism of strengthening the structural rigidity of the first floor of high-rise suspended buildings; and proposes a design optimization theory of gradually strengthening the high-rise suspended buildings along the height. In addition, spring elements are introduced to simulate the nonlinear dynamic interaction between piles and soil, and the most unfavorable state of the slope strike and the direction of the suspended floor is given; safety design suggestions such as adjusting the design direction are also put forward. In view of the uneven stiffness of high-rise suspended buildings, a self-restoring vibration reduction technology for high-rise suspended buildings and an optimal design method for suspended suspended buildings based on floor damping energy consumption requirements are innovatively proposed. A new self-restoring beam-column joint form is designed, and a self-restoring calculation model based on phenomenology is proposed, which effectively solves the problem of insufficient earthquake resistance caused by complex forces and severe damage of high-rise suspended buildings. 2) Full-process dynamic construction technology for discontinuous multi-level slopes Considering the impact of load changes caused by foundation pit excavation, building construction and backfilling on discontinuous slopes, a simple foundation pit support system and its construction method for mountain building slopes were developed. A method for reducing load in foundation pit excavation was proposed for the first time, which solved the support construction technology for multi-level slopes in the foundation pit excavation environment; In addition, a jacking device for foundation pit support and an anchor cable pile sleeve positioning device and its use method have been developed, which solve the problems of increasing building loads on slopes and multi-level slope support construction under fill, and ensure the overall safety and stability of multi-level slopes. 3) High-rise pendant building single construction technology Aiming at the steep environment around the high-rise pendant building, an efficient and safe high-rise pendant building single construction technology has been developed that considers the collaborative effect of the pendant part and back backfilling. In addition, tools and construction methods such as hillside tower crane foundation construction devices have been developed, which has accelerated material turnover under steep slope conditions and improved construction efficiency and quality. 4) The construction technology of suspended building groups under multi-level steep slope conditions combines the terrain trend of the project and the distribution of suspended buildings to develop a construction planning and schedule control method for high-rise suspended building groups under multi-level steep slope conditions. The load increase method of suspended building groups under steep slope conditions is determined and optimized through step, zoning, step-by-step, and time-sharing (the construction speed difference is based on a minimum value of 100%/n+5Delta; numerical control) to balance the load distribution in the entire steep slope area and ensure the overall safety of suspended building groups and slopes. This project has been authorized 12 invention patents; authorized 8 utility model patents; published 7 domestic and foreign papers (2 included in SCI and 1 included in EI); won 1 China Patent Excellence Award; won 2 provincial and ministerial construction methods; and its scientific and technological achievements have passed provincial and ministerial appraisals (internationally advanced). This project has been successively applied in projects such as Wanshuo in Chongqing and Wangmo in Guizhou. It has solved the technical problems of the design and construction of high-rise suspension buildings under multi-level steep slopes. The construction is safe and reliable, and the construction period is saved by 10%. The cumulative new output value in the past three years has been 204.7 million yuan, creating profits of 11.49 million yuan, filling a technical gap in this field, providing complete solutions for the construction of similar projects at home and abroad, and is of great significance to promoting the safe, efficient and green development of mountainous buildings.
