摘　　要：为了对岩溶区嵌岩基桩的承载特性开展更深入的研究,自行研发了岩溶区嵌岩基桩室内模型试验系统。该系统主要由模型箱、加载系统、测试系统以及溶洞模拟技术等组成。鉴于较少开展岩溶区嵌岩基桩室内模型试验,提出了试验用岩溶地基制备以及试验操作方法,通过室内模型试验证明了该方法的可行性。另外,与现场实测结果进行对比,表明利用该试验系统进行嵌岩基桩室内模型试验是可行的。In order to make further researches on the bearing capacity of rock-socked foundation pile of karst area, a indoor model test system was established. The development system consists of the model test box, loading system, measuring system and simulation techniques of karst cave. In view of the indoor model tests of rock--socked foundation pile of karst area were less carried out, the preparing methods of making karst foundation and test operation are introduced. The final test results show that this method can meet the requirements of the following experiments. Furthermore, comparing with the full-scale load test, by use of this model test system, the test results are feasible.
