Tanah lempung ekspansif memiliki kembang dan susut yang sangat besar, dimana pengembangan terjadi pada musim hujan dan menyusut pada musim kemarau. Hal ini menyebabkan rendahnya daya dukung tanah dan berakibat pula pada kekuatan struktur yang akan dibangun di atasnya. Penelitian kuat dukung tanah dengan perkuatan kolom SiCC sudah dilakukan sebelumnya, namun karakteristik kuat geser tanah di sekitar kolom SiCC belum dikaji. Sehingga, pada penelitian ini dilakukan penelitian lanjutan untuk mengkaji kuat geser dan perilaku tanah disekitar kolom SiCC. Pada penelitian ini, kuat geser tanah disekitar kolom SiCC diuji dengan triaksial kondisi UU dan CU. Tekanan sel yang diberikan pada kondisi UU sebesar 49,05 kPa, 61,31 kPa, dan 73,58 kPa. Sedangkan tekanan sel yang diberikan pada kondisi CU sebesar 98,1 kPa, 196, 2 kPa, dan 294, 3 kPa. Tegangan aksial diberikan melalui tegangan deviator dengan kecepatan pembebanan 1,674 mm/menit pada kondisi UU dan 0,05 mm/menit pada kondisi CU hingga benda uji mencapai keruntuhan. Hasil penelitian menunjukkan bahwa kekuatan dan kekakuan tanah lebih tinggi terjadi di dekat kolom SiCC dan menurun dengan jarak dari pusat kolom SiCC.
