补充资料：岩土体蠕动
岩土体蠕动
creeping of rock mass and soil mass
yol、ltjtl rLJdo了、g岩土体蠕动(creeping of roek mass and 5011mass)斜坡岩土体在坡体应力长期作用下发生的一种缓慢而持续的变形现象。蠕动开始时运动速率极为缓慢，往往不易觉察。蠕动常是急剧变形破坏的先兆，随着蠕动进一步发展.坡体不断松弛变形，直至发生突然的崩塌或滑坡。意大利瓦依昂(Va」ont)水库于1963年发生近3亿m“的巨型滑坡.在失事前3年已观测到有蠕动迹象，在滑坡即将发生前.其蠕动速率明显增大。 蠕动体类型分为土体蠕动和岩体蠕动两类。土体蠕动多发生在粘性类土中，土体在干湿或冻融交替、或处于饱和等情况下.土体强度明显降低，在重力作用下很易产生蠕动。岩体蠕动主要是重力、地应力等各种力长期作用的结果。按蠕动变形特征，可分为倾倒型、扭曲型、松动型、塑流型等类型。闭倾倒型。多发生在陡倾角层状结构、由脆性岩石组成的斜坡。其变形特征是岸坡岩层向临空一侧折裂和倾倒，岩体呈现松动架空现象。②扭曲型。主要发生在陡倾角、薄层的塑性岩层(如页岩、千枚岩、片岩等)或软硬互层的斜坡。其变形特征是岸坡岩层向临空侧歪斜，多呈现塑性弯曲，俗称“点头哈腰”，但很少折裂。③松动型。多发生在中厚层脆性岩石组成的反倾向斜坡，或由倾倒型进一步发展而成。其特点是岩层层序已错位扰动，松动架空现象严重。④塑流型。发生在坚硬岩层下伏有软弱岩层的斜坡，当软层产生塑性变形时.导致上覆岩层的蠕动，甚至解体和下沉挤入软层中。 防治在选择建筑场地时，应尽量避开蠕动体。对于建筑场地出现的蠕动迹象，需及时采取包括消除或减轻地表水和地下水的危害，改善边坡岩土体的力学强度或采用支挡建筑物、锚固等工程措施.以制止蠕动的进一步发展。
