巖薄荷 的英文怎麼說
中文拼音 [yánbóhé]
巖薄荷
英文
dittany-
In this paper, it is studied and analyzed characteristic of stress, distortion etc. of pipe liner structure combining dahuofang transport water tunnel practice project, tunnel boring machine construction, and it is considered that affects internal force of pipe liner for early stress of underground structure and digging load. in nonlinear finite element calculation model, folium cells have been simulated among pipe liner and pipe liner and wall rock. under varies load condition, it has educed that changing rule of stress, distortion and load characteristic pipe liner in kinds of wall rock tunnel by analysis and calculation
本文結合實際工程，分析研究了大夥房水庫輸水隧道工程在採用掘進機施工方法的情況下，利用管片襯砌的結構應力、變形等受力特性，考慮地下結構初始應力和開挖荷載對襯砌內力的影響，採用薄層單元模擬襯砌管片之間、襯砌管片與圍巖之間的非線性有限元計算模型，通過分析計算得出不同荷載工況下各類典型圍巖段隧道襯砌管片受力特徵、應力和位移變化規律。Therefore, in the process of load transfer within the unconsolidated confined aquifer, the key strata of overburden rock are prone to have a compound breakage when the load on the upper interface of bedrock is great and the bedrock is very thin
在鬆散承壓含水層的載荷傳遞作用下，作用在基巖頂界面的載荷較大，當基巖厚度較薄時，采場覆巖關鍵層易產生復合破斷。
