摘要
对皖中地区膨胀土的地域分布、气候和工程地质特征进行了分析,对区内几条已建公路的病害进行了调研,得到了区内公路工程膨胀土病害产生的原因、特点及规律。
Through analyse the features of distribution, climate and engineering geology for expensive soil in the middle of AnHui province, geological environment of generating expensive soil plant disease in road is explored. Investigate several roads that have constructed in this area, the result shows that the plant disease have some similarity, principal plant disease is split crack, shoulder of the road outside leans, the shallow layer slips of slope and the retaining wall drum to outside. Finally, unifies the features of expensive soil in the middle of AnHui province and the road plant disease characteristic carries on the generalized analysis, obtained the reason, the characteristic and the rule which the highway engineering expensive soil plant disease produced in this area, provided the explicit instruction for the design and the construction of expensive soil handling plan in constructing and plans to construct highway.
