渗透变形渗透变形seepage deformation sherltoLJ匕旧nx一门g渗透变形(seepage deformation)由于渗流引起土体或土颗粒移动而导致的土体变形或破坏。土体的渗透变形形式通常归纳为管涌、流土、接触流失和接触冲刷4种。它与地质条件、土的性质、颗粒组成及结构、水力条件和渗流出口的保护条件等因素有关。对单一土层结构，主要是管涌和流土，对双层结构土层或土层与建筑物(或岩体)界面处主要是接触流失和接触冲刷。在实际工程中，首先要判别渗透变形的可能形式，然后确定其抗渗强度，并采取必要的防护措施。 渗透变形形式①管涌，指颗粒骨架间的孔隙中细颗粒被渗透水流移动和带出的现象。若在某一水力比降(作用水头和渗径长度的比值)下，这种现象连续发展，而且渗透系数增大，则称为发展性管涌;若增大水力比降后带出一些细颗粒，随后又停止，渗透系数也不增大，则称为非发展性管涌。管涌常发生在颗粒组成很不均匀的砂砾石地基中。②流土，指某一局部土体整体隆起、浮动和流失的现象，常发生在较均匀的砂土或猫性土的渗流逸出面上，随后向深部发展。③接触流失，指两种不同粒径的相邻土层接触面处，由于垂直层面的渗流使较细土层中的土粒向相邻较粗土层孔隙中流失的现象。④接触冲刷，指渗流沿两种不同粒径的相邻土层或土层与混凝土建筑物(或岩体)界面带走细颗粒的现象。 判别方法试验是判别渗透变形形式和确定抗渗强度的有效方法。试验研究表明，勃性土及不均匀系数C。<(5一10)的无勃性土.渗透变形形式主要是流土;C。>10的无勃性土，渗透变形形式主要取决于细粒含量P。P>35%时为流土;P<35%时为管涌，其中P<25%时为发展性管涌，P一(25%~35%)时为非发展性管涌，最后破坏形式主要决定于土的密度与结构，可能是流土，也可能转化为发展性管涌。对于双层地基，当细粒土的C。<10，且Dl。/dl。簇10时，一般不会发生接触冲刷;两层间满足反滤要求时不会发生接触流失。Dl。和dl。分别为粗粒土层和细粒土层的特征粒径，小于该粒径的土粒重为总土重的10%。 抗渗强度土体抵抗渗透破坏的能力，以临界水力比降(亦称破坏水力比降);，表示。流土的;‘值可按动水压力和土的浮质量平衡的原理，由下式确定 _尸之f一—一气t，，—1从1—11， 尸，式中洲是土体浮密度;Pw是水的密度;以是土粒比重;n是孔隙率。管涌土的破坏水力比降可用试验方法确定，或用经验公式作初步评价。土体的抗渗强度还与渗流出口的防护条件有关，反滤层可提高土体的管涌破坏比降，反滤层及透水盖重可使被保护土体免于流土破坏。
