泄水减压技术在地铁车辆地下停车场结构抗浮设计中的应用
|
摘要
青岛地铁13号线灵山卫地铁车辆地下停车场采用了泄水减压抗浮技术。首先进行了抗浮技术方案的比选及泄水减压抗浮技术的适用性分析,然后从泄水减压抗浮原理、基坑涌水量、盲沟布置及泄流能力、水位监测等方面详细阐述了泄水减压抗浮系统的设计,最后分析了实施泄水减压抗浮方案对周边环境的影响及需要采取的防护措施。该技术较好地解决了抗浮问题,节省了工期,节约了投资。在地形利于地下水排泄,地下水的分布、渗流、涌水量等因素可预测的情况下,泄水减压技术是一种可应用于地下工程的绿色、环保的抗浮技术。
Lingshanwei metro underground parking of Qingdao metro line 13 adopts the water-discharging and pressure-relieving technique.Firstly,the comparison of anti-floating technique schemes and the applicability analysis of water-discharging and pressure-relieving technique were carried out. Then,the design of water-discharging and pressure-relieving for anti-floating system was elaborated in detail from the aspects of the principle of waterdischarging and pressure-relieving for anti-floating,the inflowof foundation pit,the layout and discharge capacity of blind drain,and the water level monitoring. Finally,the influence of water-discharging and pressure-relieving for anti-floating scheme on the surrounding environment and the protective measures needed to be taken were analyzed.The technique can solve the problem of anti-floating,save time and investment.U nder the condition that topography is conducive to the discharge of groundwater,the distribution,seepage and inflowof groundwater can be predicted,the water-discharging and pressure-relieving technique is a green and environmentally friendly anti-floating technique which can be applied to underground engineering.
