In construction of field stations located in sandy soil areas with higher ground water levels , the ground water level must be lowered below designated excavated depth so as to guarantee the smooth engineering progress 摘要在水位较高的砂土地区进行站场施工，必须先将地下水位降到设计挖深以下，才能保证工程的顺利进行。
What do the yellowjohns of anglia owe us for our ruined trade and our ruined hearths ? and the beds of the barrow and shannon they won t deepen with millions of acres of marsh and bog to make us all die of consumption 他们不肯把巴罗河和香农河385的河床挖深，以致好几百万英亩良田都成为沼泽和泥炭地，足以害得咱们大家全部死于肺病。 ”

After secondly testing and investigating carefully , it indicates that there are a lot of unfavorable geological road section and a long distance is about 39 . 78km , is 28 . 2 % of the whole road . it is worth mentioning that most parts of the road is in new road . the max depth of filling is 33 . 6m and the max depth of cutting is 32 . 2m ; the great quantity of engineering , the difficulty of the technology , and the complexion of the construction are highest in all of province roads 通过路线复测和详细调查了解到，地质不良路段多、里程长，全线共39 . 78公里，占全线总长的28 . 2 ，且大部分处于新线。路线最大填高达33 . 6m ,最大挖深32 . 2m ，工程量大，技术复杂，施工难度堪称全省公路建设之最。
