[0002] With the development of building technology, various formwork systems must be used in the construction of cast-in-place concrete structures. In the construction of cast-in-place concrete structures, formwork collapse accidents often occur. The main reasons for formwork collapse safety accidents are various, such as excessive formwork load, excessive formwork deformation, insufficient formwork support frame foundation bearing capacity, etc. Due to the above reasons, the formwork support frame components fail, partial collapse or overall instability occurs, leading to engineering damage and on-site personnel casualties. With the development of social economy and the progress of science and technology, the scale, space and volume of construction projects are gradually increasing, and the plane and elevation of buildings are more complex and diverse, so higher requirements are needed for the safety management of formwork construction.

[0003] In the analysis of formwork collapse and instability accidents, accidents caused by foundation problems account for a large proportion. If the formwork support frame foundation treatment is not in place or not strictly constructed according to the construction specifications, the foundation bearing capacity will be insufficient, settlement will occur during concrete pouring, and excessive deformation of the support frame will occur due to the sinking of the support frame, which is the main cause of formwork safety accidents.
