연약지반을 매립후 굴착을 시행할 경우 흙막이벽체를 설치하더라도 배면지반에 지반파괴가 발생한다. 이를 최소화하기 위해 억지말뚝을 적용 후 실내모형 실험을 시행하여 억지효과를 규명하였다. 모형토조내 점토를 충진하고 계측시스템을 이용하여, 무보강일 경우와 억지말뚝으로 보강한 경우를 설정하여 굴착에 따른 배면지반의 침하, 간극수압, 토압을 측정하였다. 모형실험 결과 억지말뚝으로 보강할 경우 무보강시와 비교할 때 굴착 단계의 증가와 배면지반의 침하가 감소된 것으로 평가되었다. 간극수압은 보강여부와는 크게 상관없었고, 침하율은 적게 나타났다. 또한, 굴착깊이가 배면지반에 매우 큰 영향을 미치고, 굴착지점과 가까울수록 최대 침하가 발생되는 것으로 평가되었다. When conducting excavations after burying the soft ground, even if the retaining walls are installed, failure often occurs within backfill. In order to minimize the occurrences of failures, model test was performed after the installation of stabilizing piles to investigate the stabilizing effects. The model chamber is set up with clay foundation reinforced with and without stabilizing piles. During the excavation of clay foundation, the subsidence, pore water pressure, and soil pressure along the excavation were measured. As a result of the model test, the increase of excavation levels and the reduction of subsidence of back ground were observed with the stabilizing piles, compared to those without the stabilizing piles. The installation of stabilizing piles does not influence the pore water pressure change, but induces less subsidence rate. In addition, the depth of excavation has a significant effect on the back ground and it was evaluated that the maximum subsidence occurs as it is closer to the excavation point.

Objective The aim of this study is to investigate if Sweet Bee Venom(SBV) Therapy has the equal effect in comparison with Bee Venom (BV) Therapy on Chronic Lower Back Pain. Methods Clinical studies were conducted to 39 patients who were treated Chronic Lower Back Pain in Dept. of Acupuncture and Moxibustion, Dongeui University from March 1 to June 30, 2008. Subjects were randomly devided into 2 groups : BV treated group(Group A, n=19), SBV treated group(Group B, n=20) In BV treated group(Group A), we treated patients with dry needle acupuncture and BV Therapy. In SBV treated group(Group B), we treated patients with dry needle acupuncture and SBV Therapy. All process of treatment were performed by double blinding method. 1. To estimate the efficacy of venom in controlling pain, we have checked Visual Analog Scale(VAS). 2. For evaluating functional changes of patients, we have checked Oswestry Lower Back Disability Questionnaire(ODI). 3. To estimate Itching which is the most prominent symptom of allergic reaction, we have checked Visual Analog Scale(VAS). Results 1. In controlling pain, the results of BV treated group(Group A) is more effective than that of SBV treated group(Group B). 2. In promoting function, the results of BV treated group (Group A) is more effective than that of SBV treated group(Group B). 3. In controlling itching, the results of SBV treated group(Group B) is more effective than that of BV treated group(Group A). Conclusions According to the study, SBV Therapy shows more effective result than BV Therapy in controlling itching. But BV Therapy is more effective than SBV Therapy in controlling pain and promoting function.
