江洋畈生态公园人行木栈桥沉降观测

摘要

Jiangyangfan eco-park pedestrian bridge was built in September 2010,but it sank more than 200 mm only four months later. We have been monitoring the settlement from January 2011 in order to assure continuing safety. The result shows that all the settlements are caused by the peat soil under the PE pipe footings.%江洋畈生态公园人行木栈桥于2010年9月建成后仅4月，桥面沉降达200mm。为保证木栈桥的安全运营，从2011年1月开始对木栈桥沉降进行了观测。结果表明，桥面沉降全部是PE管悬浮基础下西湖疏浚泥炭质土的沉降。
