摘要
分析了建筑物混凝土基础底板的主要开裂原因,研究了试验模型和试验方法。通过实际工程天都花园建筑混凝土基础底板的开裂情况,利用相似原理建立开裂分析试验模型,模拟基础底板的温度场和约束条件,研究分析底板开裂。根据试验结果,分析讨论了混凝土底板的裂缝,得出相应结论以及对实际工程的意义。
This paper has analysed main reasons of the cracking on the concrete foundation mat of the biuding, reasearched on experiment model and method of the test . Through cracking circumstance of the concrete＇s foundation mat of the building on real engineering of TIANDOU garden, we established the test model of the cracking analysis by similar principle, and simulated temperature field and restraint conditions, reseached on cracking of the concrete groundwork. Acccordung to positive result of the test, we analysed the crevice of the concrete groundwork, got a conclusion and discussed its value to the actual project.
