地下連續墻是一種歷史較短的施工方法，目前，砼防滲墻的設計還是以傳統的設計方法為主，根據查找國內外文獻資料，華東建築設計院王衛東利用地下連續墻與樁在豎向荷載作用下的工作性能有相似性，將適用於樁基的poulos彈性理論引入對地下連續墻的沉降計算中；清華大學水利水電工程系濮家騮、于玉貞根據三軸試驗結果確定混凝土的參數，利用非線性e - b模型，結合黃河小浪底土石壩設計剖面，採用thepd土石壩總應力程序，對深覆蓋層塑性混凝土防滲墻的應力、位移進行有限元分析，並與普通混凝土防滲墻計算結果加以對比，同時分析了不同配比塑性混凝土特性的影響，並採用應力水平和拉應力數值來判斷塑性混凝土防滲墻的安全程度。Such a model of egg production would be benefit this species to survive in this waters area and become a dominant species. for subitaneous eggs, in winter - spring with long hatching time, the females lay in nighttime in upper water layer. the distance for eggs sinking to the sea - bottom is also long
對于滯育卵來說，雌體日間在海區下層水體產卵，可使得滯育卵快速沉至海底，縮短滯育卵在水體中的滯留時間，降低在水層中被攝食的風險，同樣也有利於個體的存活和種群的延續。Because of its advantages in traversing the channels, with the development of the national economy, immersed tunnels will inevitably be used as the main means of traversing rivers, bays and seabeds. in the cities divided by rivers over bays, immersed tunnels have great superiorities in connecting the different parts
