As the pre - evaporation time increases, the holes on the membrane surface becomes smaller and less, dense layer is becoming more evident with large and deep holes in supporting layer ; and porosity increases as well - as average hole diameter decreases
隨著預蒸發時間的延長，膜表面的孔變小變少，膜的緻密層越來越明顯，支撐層有大而深的孔結構出現。隨著預蒸發時間的延長，膜的孔隙率上升，平均孔徑下降。 -
On the basis of construction technique of large diameter bored hollow pile of prestressing force concrete, through the program of marc, this paper analyses the pile vertical bearing capacity under different lengths, diameters and strength parameters of mediators as well as the inner force and displacement under lateral and combined loads, giving the criterion of rigid pile and flexible pile. with elastic theory, the paper establishes the inner force calculating formula under eccentric load. this research findings will set a firm theoretical foundation for its widely application
本文在對大直徑鉆埋預應力混凝土空心樁施工工藝分析研究的基礎上，運用marc軟體，對豎向荷載作用下不同樁長、樁徑及樁周介質強度參數時空心樁的承載力性狀，以及水平向荷載及其組合荷載作用下空心樁的內力、位移變化規律進行了模擬分析，提出了大直徑鉆埋預應力混凝土空心樁的剛性與柔性界定標準。 -
By means of numerical emulation, it analyses the pile vertical bearing capacity under different lengths, diameters and strength parameters of mediators as well as the inner force under lateral and combined loads, giving the criterion of rigid pile and flexible pile. with elastic theory, the paper deduces the inner force calculating formula under eccentric load and the bearing capacity calculating formula under vertical load ; establishes a complete design and calculating method of large diameter pile
通過數值模擬，對樁在豎向荷載作用下不同的樁長、樁徑及樁周介質強度參數變化時樁的承載性狀進行了分析，並對樁在水平向荷載及其組合荷載作用下樁的內力變化規律進行了分析，提出了大直徑鉆埋預應力混凝土空心樁的剛性與柔性界定標準。 -
Thames water pipe ( 2. 2 m ) suffered three damages along the pipeline asymmetrically spaced around the fault in kocaelie earthquake, and the shigang water pipe ( 2. 0 m ) suffered two damages along the pipeline symmetrically spaced around the fault in ji - ji earthquake. the failure performance of these two damage cases for large diameter steel pipelines are much different form each other because of the different types of fault movements as well as the type of soil condition on both sides of fault ( kl k2 and kl = k2 )
利用本文所提出的殼有限元模型，對兩類埋地管道通過斷層的實際震害進行了模擬：第一類是在供水管網系統中占據重要位置的大口徑鋼管的震害，土耳其地震和集集地震分別都有這類管子的震害；第二類是以往震害資料很少的pe管在集集地震中的震害。 -
