摘要： 松木桩适宜在地下水位下工作，能很好的防止地下水和细菌对其的腐蚀，具有施工速度快、工艺简单、造价低等优点，作为构造物基底处理已使用多年，且效果不错。结合广州南沙某用地平整及软基处理项目，提出了松木桩用于围堰基底处理的设计方案。经过处理后，基底淤泥层的模量和承载力均得到一定程度的提高，相比于搅拌桩，在达到相同处理效果的前提下，可节约造价，经济效果显著。该方法安全、高效、经济地解决了高压缩性土上施工围堰结构的难题。

Abstract: The submerged pine timber gains the reputation of “lasting for thousands of years” and it is well suited for the applications of under groundwater conditions that can minimize the deterioration caused by the bacteria attacking. The timber pile also has the advantages of fast construction, simply application and cost effective and it has been used for many years. This paper presents a case of timber pile applying in as the foundation treatment for a cofferdam in a soil improvement project in Nansha, Guangdong province. After timber pile treatment, both the combined modulus and the bearing capacity of the mucky soil within the cofferdam were improved.
Key words: Pine Timber Pile, Pile Deterioration, Cofferdam； the basal reinforcement
