一、概述为研究水下填土工程的抛填特性,我们在一座长50米,宽2米,深6.5米的矩形水槽中,进行填筑体的断面模型试验,目的是探求: 1.风化砂砾料及粘性土料的水下填筑性质; 2.适宜于水下填筑的施工方法及断面型式。同时,以长5.6米、宽0.5米、高1.0米的玻璃水槽和长1.4米、内径0.12米的塑胶筒来分别测求试验土料的渗透系数K,并用容积为500厘米~3的环刀取样,测求容重、比重、颗粒分析、击实、湿化等。试验时,槽内水深分别为2～6米,填筑方法
I. Overview In order to study the thrown-in characteristics of underwater fill works, we conducted a cross-sectional model test of the reclaimed body in a rectangular tank 50 meters long, 2 meters wide and 6.5 meters deep. The purpose is to explore: 1. Weathered Sand and gravel materials and clay materials underwater filling properties; 2. Suitable for underwater construction methods and cross-section type. At the same time, with the length of 5.6 meters, 0.5 meters wide, 1.0 meters high glass sink and 1.4 meters long, 0.12 meters in diameter plastic tube were measured permeability of the test material K, and with a volume of 500 cm ~ 3 ring knife Sampling, determination of bulk density, specific gravity, particle analysis, compaction, wetting and so on. Test, the tank depth of 2 to 6 meters, filling method
