新疆南疆某机场岩土工程勘察若干典型问题分析
|
摘要
拟建场地位于新疆南疆阿克苏地区,为库车河冲洪积平原区,地势相对平坦,建设项目有机场跑道、航站楼、办公楼及附属建筑等。勘察过程中除常规的钻探外,还通过抽水试验、现场浸水载荷试验、标准贯入试验等对岩土特性及不良土体进行了测试分析,对地下水、砂土液化、腐蚀性、盐渍土等进行了分析,总结了沙漠干旱区进行岩土工程勘察时需注意的问题。
The proposed site is located in the Aksu area in southern Xinjiang, which is the Kuche River alluvial plain. The terrain is relatively flat. The construction projects include airport runways, terminal buildings, office buildings and ancillary buildings. In addition to conventional drilling during the survey, the geotechnical characteristics and the bad soil were tested and analyzed by pumping test, on-site immersion load test and SPT. Though Groundwater, sand liquefaction, corrosive and saline soil were analyzed It was summarized the problems that should be paid attention to when conducting geotechnical investigations in desert arid areas.
