填海区地下水的抗浮水位和腐蚀性的探讨——以深圳前海填海区为例

Reclamation of Anti-floating Groundwater Level and Corrosion Resistance——Example of Shenzhen's Land Reclamation

通过建立填海区的地下水水位及水质监测网络,长期观测该片区地下水水位、水质,研究地下水水位、水质随海水潮汐、大气降水、人类活动等因素在时间及空间上的变化。监测结果显示大面积填海造陆后,填土(石)内形成了新的自由水面,常年稳定存在,该层地下水对工程的抗浮设防及腐蚀性产生重要的影响,地下工程建设前应对其重点监测。

Through the establishment of groundwater level and water quality monitoring network in the reclamation area,long-term observation of groundwater level and water quality in this zone,the study of the change in groundwater level and water quality as well as the tide of seawater,atmospheric precipitation,human activity and other factors in time and space. Research results show that the large area after reclaiming land from the sea,filled soil（ stone） to form the new free surface stably,the layer of groundwater in engineering anti-floating fortification groundwater level has important impact on corrosive,before the construction of underground engineering,which should be key monitored.
