Abstract

Harga Cb diasumsi sebesar 2Cv dalam perencanaan sistim perbaikan tanah pada jalan To I Surabaya-Mojokerto. Besar pemampatan sekunder tidak dihitung padahal pemampatan konsolidasi akan berakhir dalam waktu yang sangat pendek. Untuk membuktikan barga Cb asumsi, dibuat trial embankment di lapangan. Data pemampatan lapangan diplot bersama-sama dengan basil prediksi pemampatan yang dibuat dengan variasi harga Cb. Kurva-kurva yang berimpit menunjukkan Ch asumsi benar. Harga Cb juga ditentukan dari derajat konsolidasi, basil prediksi pemampatan dan data lapangan; harga yang saling mendekati berarti asumsi Ch benar. Besar pemampatan sekooder ditentukan dengan formula yang tersedia. Data lapangan dari ST A 9+625 tidak bisa dipakai karena hasilnya tidak akurat. Besar Cb lapangan yang ditentukan dari data pada STA 9+775 adalah l.5Cv-2Cv. Pemampatan konsolidasi diprediksi akan berakhir pada 28 Oktober 2009 untuk STA 9+625 dan 21 Mei 2009 untuk STA 9+775. Besar pemampatan sekunder diprediksi sebesar 1.74 m pada STA 9+625 dan 1.94 m pada STA 9+775. Harga tersebut tidak sepenuhnya dapat dipakai karena data yang diperlukan tidak tersedia

The Cb price is assumed to be 2Cv in planning the soil improvement system on the To I Surabaya-Mojokerto road. The amount of secondary compression is not calculated even though the consolidation compression will end in a very short time. To prove the assumed Cb price, a trial embankment was made in the field. Field compression data are plotted together with the results of compression predictions made by varying Cb values. The curves that coincide indicate the Ch assumption is correct. The Cb price is also determined from the degree of consolidation, compression prediction results and field data; prices that are close to each other mean that the assumption Ch is correct. The amount of compression of the secoder is determined using the available formula. Field data from ST A 9+625 cannot be used because the results are inaccurate. The field Cb value determined from data on STA 9+775 is l.5Cv-2Cv. Consolidation compression is predicted to end on 28 October 2009 for STA 9+625 and 21 May 2009 for STA 9+775. The amount of secondary compression is predicted to be 1.74 m at STA 9+625 and 1.94 m at STA 9+775. These prices are not fully applicable because the required data is not available
