Abstract

S obzirom na temu „Ojačanje temeljnog tla dubinskim vibracijskim metodama“ u radu je inicijalno općenito pojašnjen pojam ojačanja tla zajedno sa svojom primjenom, ciljevima, tehnologijom i razvojem kroz povijest. Ciljevi kao što su povećanje nosivosti tla direktnim utjecajem na mehaničke karakteristike, smanjenje likvefakcijskog potencijala i iskorištavanje preostalih građevinskih površina u izgrađenim urbanim sredinama razlozi su sve većeg pristupa metodama lokalnog ojačanja tla. Objašnjene su metode dubokog vibracijskog ojačanja tla kao jedne od najkorištenijih metoda ojačanja temeljnog tla. Kroz njene varijacije kao što su duboko vibracijsko zbijanje, dinamičko i brzo udarno zbijanje, miniranje te šljunčani piloti direktno su prikazani rezultati primjene ove metode. Za svaku metodu priloženi su primjeri iz prakse kako bi se približio praktični rezultat primjene, kao što je zbijanje nasipnog lukobrana u Ičićima, temeljenje 137 urbanih vila u Dubai-u, temeljenje uređaja za pročišćavanje voda Petrinja, temeljenje Župne crkve Presvetog srca Isusovog.

Abstract (english)

Since the topic of the paper is "Strengthening of the foundation soil using deep vibratory methods", the paper initially describes the concept of soil improvement along with its application, goals, technology and development throughout the history in general. Goals such as increasing the bearing capacity of the soil by directly affecting the mechanical characteristics, reducing the liquefaction potential and utilizing the remaining construction areas in built-up urban areas are the reasons for the increasing use of the local soil strengthening methods. Methods of deep soil reinforcement are explained as one of the most used methods of strengthening the foundation soil. Through its variations such as deep impact compaction, dynamic and rapid impact compaction, use of explosive and gravel piles, the results of the application of this method are directly presented. Examples from practice are also added for each method in order to approximate the practical side of using deep vibratory tecniques, such as the compaction of the embankment breakwater in Ičići, the foundation of vi 137 urban villas in Dubai, the foundation of the Petrinja water purification device, the foundation of the Parish Church of the Sacred Heart of Jesus.
