引江济淮工程膨胀岩特点浅析

摘要

In the south section of Huaihe river for the diversion of water from Yangtze river to Huaihe river project ,there locates lots of swelling rocks along the water conveyance line ,which could influence the stability of the slope of the diver-sion channel .This paper discussed the distribution , engineering geological features and treatment of swelling rocks .In order to ensure the project safety ,the measures of treatment are proposed .%引江济淮工程淮河以南段的输水线路沿线分布有较多的膨胀性软岩，其对引水渠道边坡的稳定性有一定影响。对膨胀岩的分布特点、工程地质特征和处理建议进行简要评述，根据其在渠道中的切深、泥岩占比及泥层自身膨胀性等因素，采取与膨胀土一并处理或设置非预应力锚杆等有针对性地处理措施，保证工程安全。
