摘　　要：滇池流域为高原湖相沉积地区,土层大部分为中高压缩性深厚软土,含水量较大,有机质含量较高,天然地基承载力、抗剪强度均较低,在此类岸边上的建(构)筑物,有时会出现不均匀沉降和岸坡失稳导致较大变形的问题。本文通过某桥台变形的治理,分析了产生这个问题的主要原因可能是由于岸边效应引起的,提出了在滇池的岸坡地区修建建(构)筑物应注意的岩土工程问题。The Dianchi basin is a lake sediment area where there are multi-layer thick soils with the middle-high compressibility, the high content of water and organism, the low bearing capacity and shear strength. Sometimes, buildings constructed on this kind of bank slope involve the problems such as the big deformation caused by uneven settlements and the bank slope failure. According to the treatment of the deformation in certain bridge abutment, it＇s analyzed that the problem mentioned above is primarily caused by the shore effect, and some issues on geotechnical engineering which need to be attended are put forward when buildings are constructed on the bank slope in Dianchi basin.
