“沟浜”是残存于表层土中的河沟。其明露于地表者谓“明浜”;而暗藏于土层中者称“暗浜”。它们的共同特点是周围淤泥层厚,且夹杂腐植物多,含水量大,土层性质变化很大,其强度远远达不到建(构)筑物对地基土的承载力要求。如不认真处理,常会引起地面建(构)筑物的不均匀沉降。我们施工的上海浦东国际机场飞行保障设施区工程中沟浜纵横,其深度约为
“Gully” is a gully that remains in the surface soil. Those who are exposed to the earth’s surface are said to be “bright”; those who are hidden in the earth are called “dark clams.” Their common feature is that the surrounding silt layer is thick, and there are many rot-containing plants, the water content is large, and the nature of the soil layer changes greatly. The strength of the soil is far short of the bearing capacity requirements of the building (structure) on the foundation soil. If not handled carefully, it often causes uneven settlement of buildings or structures on the ground. The construction of the Shanghai Pudong International Airport’s flight support facilities project has a vertical and horizontal ditch. Its depth is approximately
