原地应力 meaning in English
in-situ stress
Examples
- Code of hydraulic fracturing and overcoring method for in - situ stress measurement
原地应力测量水压致裂法和套芯解除法技术规范 - Today , cast - in - situ piles are more widely used in deep foundation engineering because of their many advantages , such as better adaptability to various ground condition , providing enormous bearing capacity by a single pile and smaller dosage of reinforcing steel bar . but , their own disadvantages , such as sediment under tip , clay slurry around pile , friction and tip resistance disagreement and initial ground stress freeing , limited their bearing capacity , lowered the utilization ratio of material and increased the settlement
灌注桩，因其对地层适应性强、能提供较大的单桩承载力、钢筋用量少等优点，在目前深基础工程中得到了极为广泛的应用。但是，灌注桩的固有缺陷，诸如孔底虚土；孔壁泥浆；端阻、侧阻发挥不同步；钻孔后原地应力释放等，限制了其承载力的发挥，使得材料利用率不高，沉降较大。 - The hydraulic fracturing technology has been developed into a reliable and practical method to determine the in - situ stress slate of underground caverns , self - bearing capability of wall rock of high - pressure cavern and the high - pressure hydraulic permeability of rock mass , which has been widely used in the disposal of nuclear waste , the long and deeply - buried communication tunnels and the high - pressure caverns of hydraulic power plant
摘要水压致裂技术现已发展成为确定地下洞室二维原地应力状态、高压洞室围岩的自身承载能力以及岩体高压透水性的可靠实用方法，并已经在核废料处置、长大深埋交通隧道以及水电站高压力洞室工程中得到广泛应用。
