Abstract

In order to solve the design and application problems of photovoltaic bracket foundation under red clay geological conditions in the southwest karst area, in this paper, a micro cast-place pile was optimized, and its bearing capacity, economy and surface disturbance of micro cast-in-place piles were analyzed through theoretical calculation and static load test. The results show: the micro cast-in-place pile has good adaptability and can be widely used in similar projects. Compared with similar geology and same load engineering sites, the material cost and surface disturbance of the micro cast-place piles have been reduced by about 12.25%~ 59.08% and 10%~60% respectively. In engineering design of micro cast-place pile, the vertical pull-out bearing capacity is calculated by the revised code method, the horizontal bearing capacity is taken by the critical load value determined by the test or the M value corresponding to the critical load of the similar project, which is used in engineering design as a control index with higher safety and economy.
