Recompression and normally consolidated range
WebbIstilah normally consolidated dan over consolidated digunakan untuk menggambarkan suatu sifat penting pada dari tanah lempung. Lapisan tanah lempung biasanya terjadi dari proses pengendapan. Selama proses pengendapan, lempung mengalami proses konsolidasi atau penurunan, akibat tekanan tanah yang berada di WebbVirgin Compression. Virgin compression occurs when the soil is normally consolidated and the effective vertical stress increases from the beginning to the end of the stress increment being analyzed. For virgin compression, the following equation is the primary consolidation settlement: subscripts "0" and "f" for vertical stresses mean "initial ...

Webb23.1 Introduction. In the laboratory, the consolidation of a saturated soil specimen is conducted in a device called oedometer as shown in Figure 23.1. The test is done for undisturbed soil sample collected from field. The test is done by applying incremental external loading as shown in Figure 23.2. After allowing full consolidation, the next ...
