| 摘 要： | 对静力载荷试验和旁压试验的曲线形态和测试结果的对比分析表明,旁压试验可作为公路膨胀土路基承载力原位测试的一种手段.由于膨胀土的胀缩特性,在测定和评价膨胀土地基承载力时,不仅要考虑当前状态下膨胀土的承载能力,更要考虑其运营期间的承载力衰减特性,并初步给出南宁地区膨胀土地基承载力的衰减规律. |
| 关 键 词： | 膨胀土地基 承载力 静载试验(PLT) 旁压试验(PMT) |

| Abstract: | It's shown that pressure meter test(PMT) can be used as a means of in-situ measurement of the bearing capacity of expansive ground by Comparing P-s curves and bearing capacity by PMT with PLT(plate loading test).when estimating the bearing capacity of expansive ground,Not only the bearing capacity of expansive soil under the present state but also the decay characteristics of bearing capacity during running should be considered because of swell-shrink characteristics.And the decay law of bearing capacity of... |
| Keywords: | expansive ground bearing capacity plate loading test(PLT) pressure meter test(PMT) |
