Displacement field and mechanical analysis of a creeping silo-cave and the evaluation about its popularization potentiality

Abstract

As a low-cost green building warm in winter and cool in summer, silo-cave has gradually declined in recent years for its low safety and inconvenient living condition. In the calling of energy-saving buildings worldwide, the popularization potentiality of the silo-cave in the condition of scientific design depends on its safety, comfort, and economy. In view of the lack of safety analysis with creep effect and economy evaluation, the displacement field and mechanical analyses after excavation of the silo-cave are conducted based on its simulated creep, and a series of corresponding reinforcement measures are provided to make it to be a safety silo-cave. Meanwhile, the popularization potentiality of the safety silo-cave is evaluated by budgeting its real building and living costs and comparing with those of the counterpart ground house. The results show that the building cost index and living cost index of the safety silo-cave are just 59.41% and 43.69% of those of the ground house. The research results indicate that the safety silo-cave has a great advantage and potential to be widely popularized in the modern society that advocates eco-friendly and low-carbon, which has a significant meaning for policy makers and architectural designers of green residence in suitable rural region.
