顶管施工对土体影响的现场试验研究

In-situ test research on influence of pipe jacking on soil

通过对顶管工程的现场试验,得到了顶管施工对土压力,孔隙水压力,水位以及深层土体位移和地表位移的影响,从中得出了顶管施工对土体扰动的大小及其扰动范围的规律,并从理论上分析了原因,为顶管工程的应用提供了参考。

Through in-situ test, the influence of pipe jacking on earth pressure, pore water pressure, groundwater level movement, displacement of earths surface and the rule of the degree and area in disturbed soil can be found. The theory explanation is also presented.
