Abstract:
Excessive harmful cracks may easily appear on super-long massive concrete bottom plate. Analysis and researches are made on various aspects, such as structural design, selection of concrete raw material, optimization of concrete mixing proportion, and monitoring on concrete construction technique, thermal retardation and moisture protection curing of concrete, as well as concrete temperature, etc. Construction measures are summarized for prevention and treatment of cracks on massive concrete platform bottom plate, and these measures have certain feasibility and operability.
