郑少高速公路桥头高填方工后变形监测

Post-construction deformation monitoring on thick fill adjacent to abutment of Zhengzhou-Shaolin highway

非饱和土体的理论研究落后于实践工程应用。结合郑少高速公路土体变形监测,简述分层土体沉降和土体测斜的原理与方法,研究非饱和土体变形规律,验证无砂砼小桩处理桥头跳车问题实际效果。

Theory on unsaturated soil is far more behind its using in practical engineering. Based on ZhengzhouShaolin highway soil deformation monitoring practice, the principle of deep soil settlement monitoring and its lateral displacement survey are reviewed, then the deformation discipline of unsaturated soil is studied. The measuring result ratifies the nonaggregate minipile technology in abutment vehicle jumping mitigation processing.
